I run the same MCS package racing only no aero nearly a streetcar in SCCA touring class.600/750 gives you a much higher frequency in the front vs the rear. The car will pitch a moderate amount and will have some understeer (with no other adjustments). Given that you should find that the rear is compliant enough to get power down better than with the OEM setup. Keep an eye on your front tires, I suspect they will wear faster than before relative to the rears. Don't go too much on the sway bars, use them to tune steady state (mid- turn) and then use the dampers for turn in, turn exit. With little to no aero you can run a higher compression : rebound ratio. Instead of the traditional 2:1 or 3:1 rebound to compression, try 1.5:1 rebound to compression and increase rebound based on the stopwatch.
I would be excited for data points if you can relay any feedback once on the track, or even city driving. I spun a rod bearing back in may and I am waiting on a new motor (ford is warranty-ing my motor) so my suspension project is delayed. I will have potentiometer data for the factory setup once I am back in action. It would be good to have comparative feedback to include with my baseline.

I don't think my car pitches at all and nor does it porpose. What is the mechanics of pitching? The front rates are so much higher than stock or PP1 that should resist pitching and it seems to do so. Wear tires? Yeah massive!!! I was cording new hoo hoo A7's in about 3-4 short sessions with SCCA so they are not full four 20 min sessions/day like an HPDE. I had to run the max class legal Ford FP bar in the front, near max legal camber and lower the car to min legal to control the roll and I think my tires will be OK. I run tires square and do not find too much understeer. I'm still dialing my suspension in and think a got more time to be made up. Shocks I don't know what they do so left them at the rec starting points. I'll get around to playing with them soon but I fee victorious just trying to get ahead of tire wear...I think.
Scootsmcgreggor - did you check both sides, or run the same shim stack on both sides?
Thanks Bill. I’ll do that. Correct, no license yet. Am just thinking ahead and probably overthinking it. Thanks.Have you gone to members.drivenasa.com and checked out the rules Classification /Calculator? That should help you a ton, but assume you have not gotten a Time Trial NASA license yet? Go down to the Super Touring /Super Unlimited classification section and plug it in. I would use ST2 or ST3 if you are just guessing at your Class. Good luck.
That’s great feedback and yes I think that’s where I’ll end up and just do it becauseNot sure on the class implications but that rlca bearing is one of the best handling and predictability mods I’ve done so I hope you can put it in for
Your class or say F it and do-it anyways.
