Nice progress! What are the spring rates you are going to use?

[vcosmin]

Hi, here are the spring 2.25" I/D COMPETITION COIL SPRINGS - 10.5" height and 400 lbs rate from Avouk. Probably i dont think we'll get it right from start, but after a few launches, and depending on grip, we'll change it if needed.

Curious to see how it works out for you. I've spoken with Jens Eklund about his car last summer, and he said they used the hardest springs they could find.
Theoretically, longitudinal movement of the car should be killed by the dampers and not the springs.

My car, is somewhat lighter than the s4, and i i saw some launches of a coupe using 1000lbs spring - , i quess the right combination, is hard to be found from first try

The rear spring rate is triple as the oem fitted on this car, as the car is considerably lighter the 70 N/mm should be ok for non treated track and DOT tire.
Yet there are fairly cheep and arrive fast...so no problem if we need harder one, also the shocks are double adjustable and can manage spring rate up to 180N/mm

The font spingtare is at the moment 50 N/mm can be changed costfree.

some more pics. Again Hexer is in charge of chasis, and suspension

[vcosmin]

Some updates , and in the near future, stronger driveshaft, and maybe on piece propeller shaft, as the stock one, is to long.
