Jerry,
what does your complete RS pkg do to the street ride/handling?
thx

BBiAutosport

The car will not ride stiffer under the normal driving conditions. We are currently using springs close to the factory rates and the factory shocks will handle the un-sprung frequency. We have used the Cup Car as a baseline for our StreetCup development and tailored it to the street conditions. With our alignment specifications, the track tire life is also improved.

TRAKCAR

Ill talk to Marius but whats the improvement VS stock?
Assuming, strength, durability, adjustability and stiffer?

Nizer

You're roads are relatively smooth and you need stiffer springs for serious track work. I'm not sure I see the benefit of swapping out if you're not going stiffer (or softer, though I can't imagine why anyone would).

drabe

Would these bits theoretically fit the twin turbo with some adjustment for spring rate?

KA MOTORSPORT

The Cars have quite a few differences. But something similar can be fitted.

Here are additional pictures of our BBi 991 GT3 Spring Kit Assembled. This kit significantly improves handling by stabilizing the front end with stiffer linear-rate springs that are matched appropriately for the OE dampers to maintain comfort.

mmm....swift springs. Well done. I put together a similar package myself for my old RS, and it worked extremely well.

You guys need to offer a similar spring upgrade package for the GT4.
You KNOW those will all be track rats....

BBiAutosport

Mvez,

Thank you for the positive feedback on the Swift Springs.
The feedback from our clients for this particular kit is great! It has been driven hard throughout the streets of Southern California and top circuits such as the Circuit of America. The best part about it is that it still retains the OEM lift system.

The answer to your question about the GT4 is yes, and we have one here in the shop for product development.
We are currently working on the StreetCup Suspension Package, Roll Bar, and Aero Upgrades.
