Kirkham Motorsports

KK is not serious with prices (2995$ for 4 Penske shocks/springs) I can find better for half price).

Nick has a kit on his web site (Bilstein) but not adjustable.

If you ever have others ideas ???

Thanks,

Hi Oliver,
It would recommend playing around with your shocks first. If you have adjustable valving on them, stiffen them up a bit. I can not offer a suggestion on brand or part #, but you can accomplish a lot with a tuned set of shocks! Perhaps contact Olthoff Racing? They have been racing Superformance cars for better than 17 years or so and may be able to point you in the right direction for shock valving, if not provide a solution.

Good Luck,
Mike.

Mike my current shocks are not adjustable and start leaking at the rear (the car has 5000 miles on it since I completed it in March 2015). That's why I absolutly want to replace the 4 shocks which are not adapted for race tracks or quick rides on the streets with curves. Thanks for the suggestion.

Kirkham's prices are higher than typical, but if can you find those ADJUSTABLE Penske coil over shocks for your Cobra NEW (or even used for that matter) for half price ($1,500 for 4 shocks), then buy them! That's your upgrade.

However, I call BS, unless I see proof. Show me an ad where you can get those shocks for $1,500. I might buy an extra set and put them on the shelf.

And personally, I wouldn't be bargain basement hunting for a CSX.

The folks at Cobra Automotive are top notch too. Cobra Automotive

What I wanted to tell is that you can find adjustable shocks/coil kit for half price of the Penske sold by KK !! There are others manufacturers that can provide equivalent or better products than Penske for half price !
If I cannot find what I want in the US I'll check here with shocks/coil manufacturers that can provide great products for correct price.

You may find adjustable shocks (perhaps Koni spec) and coil overs for half price, but they will not offer you the same level of adaptability and/or ride, nor will they be the same top quality of the Penske shocks that Kirkham offers for that chassis.

The Penske units supplied by Kirkham are bespoke for their cars. I REALLY doubt you'll find anything as good, let alone better, for any price.

As MrMustang mentions above, you can find cheaper shocks/coil-overs than Penske. There are Bilstein's, Koni's and QA1's off the top of my head, BUT they're not at the level of the adjustable Penske's.

Over the years here, I've read alot of reviews and I'd highly recommend a search here on the site. All the shocks mentioned are decent-to-good shocks, but there's a reason the Kirkham's use the Penske's.

But if you want to shop the "Blue Light Special on Aisle 13" for your CSX then that's your prerogative.

Good luck.

I'm not a shocks expert but the quality of the Penskes is really, really nice. No stamped junk, that's for sure.

BTW, the pics of the Kirkham suspension are from the "billet" car. Those WON'T fit. But that car drives like a dream

The Hyperco springs used by Kirkham are also top shelf products and are used by many of the current F1 teams. Those guys use the very best, regardless of price and that speaks volumes to me about the Kirkham product selection process.

Try QA1 Adjustible shocks...they have different spring loads and have several adjustoble shock settengs. I have them on my car and they work great on the street as well as the track. Easy to adjust the settings.

I'm very happy with my QA1 coilovers (front) and QA1 shocks (rear). This application will most likely require "custom" configuration, as their application catalogue doesn't list CSX or Superformance. Proma Star Double Adjustable Shocks | Custom Mount Coil-Over Shock Absorbers | QA1 Suspension

I found QA1's tech support to be excellent, and they'll need to know installed ride height and weight for front and rear, as well as which ends are needed. I believe CSX cars use 12mm mounts, but QA1 would clearly need to know that.

Cobra valley sells the QA-1 shocks and springs for CSX cars. $1198 for single adjustable shocks and springs. Set of four. http://performanceunlimited.com/cobr...cksprings.html

I put them on my SPF and love em.
