New (to me) C4S - a few questions

Recommended Posts

I bought this 2002 C4S (picture below) a few weeks ago. I've posted a few times, but now that I've had some time to look at my options for the car, I have a few questions. My goals for the car is basically to continue what Porsche started; I want the whole enchilada. In order, I'm looking for performance, great looks, and comfort. This is a daily driver, but I plan on a little track time just for fun (working on a Miata for the track).


  1. The C4S's drive-line feels pretty sloppy in comparison to my Miata. Yes, I know they're completely different cars; the Miata is a track car, and the C4S is a daily driver, but I'd like something a little more controlled from the Porsche. I've heard good things from Function-First's transmission mount inserts, and their engine mount upgrade looks like a perfect compromise of stiffness, comfort, and price. Are there better alternatives to these two upgrades, or am I on the right track?
  2. I like the lowered look from the RÜF suspension, but the wheel fitment isn't great. I want something that's simple, more flush with the fenders, and shows off the brakes, but doesn't compromise performance - nothing goofy. What sort of dimensions should I look for? I like the 5-spoke design of Avant Garde's F330 wheels, but don't think the straight lines would go with the 996's curvier lines. Looking for something like a mixture of the OEM turbo wheels and F330's with less weight and better fitment - maybe ADV.1's ADV05.1 M.V1 SL.
  3. I'd like to open up the intake a little, but don't want to increase the wear on the engine from additional silica. Evoms' V-flow looks well engineered, and Fabspeed's competition intake is supposed to sound great, but I worry about increased wear and tear. Is there anything else I can do to improve sound and performance? Would Fabspeed's cold air upgrade kit and/or an IPD plenum be worth it, or should I just accept that I can't get better sound without sacrificing durability?
  4. After I figure out the intake, I think the better-breathing engine could really benefit from ECU/PCM tuning. I don't care about MPG or octane rating. Is the EVOMSit my best option? I haven't really seen anything else.
