BF Goodrich Radial TA 245/60R15 (front) 295/50R15 (rear) are the standard tires in the wheel packages offered by Hurricane. Goodyear Billboards are available as an upgrade and special requests can be accomodated and priced accordingly.

Thanks for the comments. I haven't seen the long lokar handle. Would you be able to post some pictures? As for the axles, I don't think they are factory ford due to the narrow track but I'm sure they are similar. Steve can answer that for you. The weak link in a cobra drive line is the tires. It will be hard to break things if you aren't;t on a drag strip. If you are a drag racer, then go with the 9 inch rear. This IRS is as strong or stronger than any thing I have seen but then again thats just my opinion.

Here are some pictures of the IRS in the car.

Thanks Steve,

Good to see you on the board. Also glad to see that you guys are offering the Billboards; I really do like the look and may get a set next go around.

Some time ago, I recall the demand for Billboards was not being adequately met by Goodyear. Hurricane's offering them as an option will hopefully add to that demand, and keep Goodyear in gear.

With a little luck, I should have the brake handle in this weekend. I'll post a couple pics when I get it installed.

A lot of consideration went into the suspension design. We recognized a need for tunability and to accurately make changes you need to know where you started. In a car that weighs roughly 2500 pounds, a good wheel rate for street driving would be 200 to 225lbs. For track days and racing you would want to target 275 to 300lbs as a wheel rate. With some measurements taken from our suspension components, we can accurately calculate the needed spring rates. The Hurricane roadster would need 500 - 550 pound springs all around on Dean's car for street driving but that's not his style. We decided to use 800lbs in the front and 750's in the back from Hyperco to get a wheel rate that is just slightly under the 300lb rate we targeted. We can do the balance of the suspension tuning with sway bars. We will post more on the sway bar math as Dean gets to that point in the build. For those of you that would like to check the accuracy of your spring rate here is a calculator that makes it fairly simply.

Now I wish I had waited until this year to order and build mine.

Dean,
Looks awesome, is the frame in POR-15 or is it powdercoated? Will both be availalbe as special order from HMS?

This has been a long time coming. Good work guys.

Well the suspension is all hung on the chassis and they are assembling the brake systems. Here are some pictures of the suspension.

In this picture you can see the 1/2 inch fuel line and the begining stages of the electrical work.

When we opened the boxes for the brakes there were a lot more little parts than I thought there would be. These brakes are from the big brake kit they offer.

Very nice Dean.

Nice to see a manufacture offer different upgrades in brakes!

dlampe · #12 (**permalink**) 03-19-2010, 06:30 PM

These brakes are great but they are a long way from just open the box and bolt on. You have to know what you are doing with the safety wire to finishe this project! All of that just to put the front rotors on!

blykins · #13 (**permalink**) 03-19-2010, 06:35 PM

Hey Lampe, what did you end up doing with the engine?

dlampe · #14 (**permalink**) 03-19-2010, 08:27 PM

Brent, I went to 6.700 rods and custom pistons. The original builder traded the rods out for me and I sold the old .080 over block and pistons to a guy who could use them. It will work out fine this way. I got enough for the block and pistons to offset the cost of the other stuff I needed for the rotating assembly.

dlampe · #15 (**permalink**) 03-19-2010, 09:11 PM

Here is the last shot for tonight. The front brakes are massive. I really wanted some good brakes and Hurricane came through for me. I will give you guys the break down of the rears tomorrow.

LMH · #16 (**permalink**) 03-19-2010, 09:31 PM

Hey Dean, what size rotors are those?
Larry

mando s · #17 (**permalink**) 03-20-2010, 01:33 AM

I've never seen safety wire used on the rotors bolts. Is this normal and do most people do it?

Regards.

Maurice Butler · #18 (**permalink**) 03-20-2010, 03:04 AM

usual to run a single strand around as per bottom right

for good detail on lockwiring check out the amateur aircraft web sites
Note: the wire has to be tight between bolts or the bolts will loosen until the lockwire is tight, then the bolts won't be tight enough.

dlampe · #19 (**permalink**) 03-20-2010, 06:44 AM

Brent the rotors are the 12.19 rotors that a lot of us use on our cars. I don't think I could go any larger with 15 inch wheels.

I will also check the safety wire and tighten the loose wires. Thanks for the tips. We always use lock-tite on those bolts as well.

The rear brakes took a little more thought but with the help of some previous owners the problem was solved. It is tough to get a good emergency brake, Willwood calipers, big rotors all bolted to Ford IRS parts. Here is a picture of the parts.

That bracket is the key to making this kit work properly.

Looking good....
