Seems to me that you are purchasing this car to impress people not because you really like Cobras.


Guess I could be wrong and like I said, if I am, I apologize.

Edit: What ever the reason I hope you have fun and enjoy your Cobra.

I'm very excited about my purchase, I would like to find out all that I can about this vehicle. and this forum has been super helpful.

I would really like to hear the reasons you have one, if it's off-topic PM me.

I actually asked myself am i getting this roadster to impress people, I can't really say no because this thing impresses me so much and I don't even have it in my possession yet.

Is showing the video of it to my friends and family and their excitement about me getting it really so bad ? I think it's wonderful and I am enjoying it and so are they.

I think competition comes into play with humans no matter what, Super Bowl Sunday :-)

I just try to keep it in perspective, I truly am the type that enjoys letting my friends use and enjoy any of my possessions and I look at competition to improve my own ability with all hobbies I have.

I do understand what you're saying.

but how could you possess an item like this and not be interested in its speed or uniqueness ??
Dennis

[D111]

don't mean to but in on you guys arguing about the shaft but wouldn't you rather bust a shaft then blow a rear or transmission?

And matter of fact I haven't heard anyone mention that they have blown a BDR rear or transmission at all.

isn't having the least expensive item the weak link proper design

The reasons I believe I purchased this roadster .

I like Harleys but I don't like the thought of my flesh scraping against the pavement.

This seems the closest thing to a Harley-Davidson with less risk.

they always caught my interest even though I rarely see one in New Jersey on the road.

I'm going to be 52 in April if this was 20 years ago it would probably not be a good idea, but now hopefully I will not get too crazy with it.

I stopped at the Harley-Davidson dealer today matter-of-fact to pick up some s100 wax and leather treatment,and feel that I made the right choice risk wise. Bikes are just too risky here in Jersey lost a couple of friends over the years .

Dennis

same thing with me, always loved the Harley until I laid one down badly on my left leg. Pulled the trigger on a Cobra after ten years of searching, going to retire next year, then I'm gonna start living my teenage years all over again, but more wiser of course.

Time to shake up all my neighbors.

Enjoy your ride. tin-man

"apparently weaker",

Half shafts on a BDR compared to other replica half shafts. Stock BMW, stronger than stock or whatever, it still applies.

I stand by that statement, if offends BDR folks, well, the facts speak for themself.

FACT is, you can find more threads and instances of broken BDR half shafts on Club Cobra, by far, than you can of other replicas. Possibly, more BDR half shafts failures than ALL other replicas combined!

So, they ARE, in fact, "apparently weaker" based on the threads on this forum. Or, the BDR "apparently" has more traction than the typical replica? Or, (insert your reason/excuse here why they break_______________)?

[Jimbocobra]

Hmmmmm......facts?

[Jimbocobra]

I stand by that statement, if offends BDR folks, well, the facts speak for themself "based on the threads on this forum".

Why would anyone be offended by your opinion or actually care what you think?; particularly your supposed "facts" that are "based on the threads on this forum". Honestly, no one cares.

Of the people in the WCCC, the only half shaft that snapped during our drag strip adventures was on an SPF, two years in a row! (with the same engine as mine). The other BDR guys and myself have been just fine, that's a fact.

[madmaxx]

Half shafts are cheap, trust me you feel like a real man if you break one, which I never did in the BDR's I owned and driven. Heck I scored a 3.8 sec 0to60 with a 302 and 305 rwhp.

[Excaliber]

I don't think too many people actually care what you think...

Same here, I could care less when the BDR owners get their panties in a knot, bury their heads in the sand and refuse to accept the facts.

FACT is: There are more threads/posts on Club Cobra concerning BDR broken half shafts, broken differential's, broken CV joints, "one wheel peel" than for any other replica on this site. You can argue the point, ignore it or excuse it, but the FACTS remain.

Not an opinion, FACT.

[Jimbocobra]

Oh, more "facts", thanks for clearing that up. You're good at this.

[Excaliber]

Look, I didn't come on this thread to bash anybody, BDR or any replica. FACT is, with any replica, getting below a 4 second 0-60 run is going to be hard on the drive train. Especially a BDR without something like the up-graded M5 type half shafts (17" wheels required) or better.

I've been around here a LOT longer than you have, Jimbo, I'm no "newbie" by a long shot, unlike yourself.

[Jimbocobra]

Well, I learned a long time ago, when someone resorts to name calling, you know you have won.

I may be a "newbie", but I happen to own a BDR with 3 years of drag strip runs, autocross, hard street miles etc... and perfectly good half shafts. I don't have the upgraded BMW M3 parts, but still have plenty of sub 4's to 60.

I've seen your posts over the years, you might want to reconsider your last statement about "trashing". Might be time for you to retire, you've been getting cranky in your old age. Maybe you can park your ERA and enjoy a nice car show in your lawn chair.

you haven't had a problem with your half shafts because with the 60 ft times you have you aren't hooking up....when you eventually do get the car to hook, you'll have a window in your rear quarter where your half shaft went through.....and the 3 years of racing where? i want to call the track, because your car should not be on it without the proper safety equipment. being you so worldly with the years and years of experience, since 2008, i'm sure you know this already.

it just rubbed me the wrong way how you talked to ernie........

Give it up. There is no such thing as an M5 option, nor is there a 17" wheel requirement. Quit spewing false gospel and calling it fact.

The reality is that when a company has more of any product on the market then you are more open to failures simply by numbers. If the customers of that product put the product to harder use you again will have more failures. It's very similar to your bias to Roush engines ... if you have 1000 engines and 20 failures you are way ahead of the game to a guy that has 50 engines and 5 failures. Numbers are relative.

What type of response do you expect from Backdraft owners in a Backdraft forum?

[twin turbo]

Dennis, you can get a G-tech meter and it will tell you how quick you are 0-60 or any speed. You'll find it takes a little practice to get the best times. I too used to ride motorcycles and switched to a Cobra replica for the same reasons, my safety. Cheers.

I've only seen 2 Cobra half shaft failures and both were on Jag rear ends. The carnage was considerable for one as it broke on the outside in a high G autocross turn. It didn't roll which surprised me later as the damage to the rear of the car from the tire bashing around convinced me that no matter what I built it wouldn't use the half shaft as an upper control arm. Jus sayin'......................

[Excaliber]

I recall a thread about a Jag IRS shaft breaking on a road course, and the car DID roll. Driver was OK,,, got lucky I reckon. The way ERA modifies the half shaft, it can break, but it won't let the wheel flop around. Their methodology specifically address' the shaft as a control arm problem.

I don't recall a BDR thread about a half shaft breaking on a road course or Auto X, it seems to be limited to the drag strip. BDR's often run a faily low rear gear ratio (3.5 to 3.9 range), when you combine that with a T5 or TKO 1st gear ratio, and plenty of bite, you maximize the torque. That could be the primary factor.

The original 289 drag race cars were running extremely low rear gear ratio's, 5.13 or something wild, with slicks of course. They primarily had trouble with rear end ring and/or pinion breakage.

DV, with his Viper powered Classic Roadster DESTROYED a Ford 9" housing when the ring/pinion AND housing exploded, so anything is possible when your pushing the limits.

Roush? I wouldn't put one in my car if you gave it to me!

At what point to you give up? The BDR comes with two rear ratios, either 3.46 (most common) or 3.15. There are a few others that get mixed in, but of the 1,000 cars sold in the USA you have 95% equipped with ratios that don't meet your claim.

It's fine if you don't know enough about the cars, just don't make stuff up.

[Jimbocobra]

FWB: "and the 3 years of racing where? i want to call the track" It's Byron Dragway, give 'em a jingle. Oh, but the way, only a helmut required on test and tune days - that much I figured out in my "worldly ...years of experience, since 2008"

The way I talked to Ernie? Did you even read the post? Maybe you skipped the parts like "panties in a knot" or "newbie" etc... Why don't you take a look at some of Ernie's 15,558 posts and see the way he talks to people. I wasn't calling him names.

[Excaliber]

Well we can argue, or we can have a discussion.

M5 axle upgrade? Sorry, my mistake, that's the M3 upgrade. That option requires 17" wheels to clear the brakes. You can't just bolt in the M3 half shafts. How much is that upgrade these days? $4,000 or so, as I recall, probably more now, if it's even available anymore.

There are a number of "vendors" whom I don't care for, wouldn't seriously consider buying their parts. Roush for one, to much money, not good enough customer service and questionable reliability. Shelby is another, just to much money, in general, for my taste. I'd go with KC for my motor, or build it myself. BDR? By the time I got the options I want (like stronger half shafts and LSD) it would be very close to the cost of an SPF, which I would prefer to have anyway. There are other reasons I wouldn't want a BDR, but no need to bash anyone.

3.9 LSD is one option a guy could run with, combined with slicks and a TKO, your looking to snap a half shaft. 3.46 is close enough to 3.5 to be a reasonable number. TO low in my opinion, WAY to low for a T5.

Like all of us, I have reasons for products I like or dislike, products I prefer one over another. So what else is new?

Cashburn, the issue here isn't the "typical" BDR, it's 0-60 in the 4 second range. 3.15 rear gear ratio need not apply. So, quit making stuff up.

[D111]

so I guess there's not much that could touch these roadsters from 20 mph to 80 mph .

I figured it would weigh somewhat less than 2600 pounds I thought original cobras came in around 2300 lbs guess it's the fiberglass resin and some additional steel?
