Project Time Attack: Seup and racing discussion
 

Here is the official thread for discussion the Time Attack project car's setup and racing efforts. Post thoughts and opinions. I will also post up results and updates.

I'll start us off. There has been a recent change in the suspension setup for the car. We were originally planing on a cantilever rear setup in conjunction with some JRZ coilovers. Due to time restraints, we have ditched the cantilever rear for phase one, but may bring it back for next season.

Instead we are moving to a new custom ultra high end setup that is bolt on for the the car with Z32 rear upright. As you can see in the parts article, we are running all cusco adjustable link. Currently we are running a stock lower control arm, but this will be eventually changed to for an adjustable unit with a roll center correction. We will also add a bump steer correction.

We are currently trying to decide on the spring rate. The car comes in at jsut under 2200lbs wet with the weight shift slightly inward and forward. I was planing on retaining close to the factory f/r bias on the spring rates with a front rate of 600-700lbs. Alignment settings are up in the air.

For wheel/tire, we are going with a 9/10 width combo and almost definitely on 17's. Tire size will range from 235-245 front and 275 to 285 rear.

Let here some thoughts
