M030 Setup with Lowering Springs

Do you have ROW M030 suspension now?

Adding the ROW springs will lower the car a bit and maintain proper rake and geometry. A lot of aftermarket lowering springs get the car too low and goof up the geometry causing it to have less grip and run slower laps. Not ideal for competitive SCCA AX.

I'm running rs3 2s this year. I'll switch to the re111s as soon as I can though. I'm also running the euro m030 springs shocks and rear sway. How much do you have to do to fix the geometry?

My recommendation is to stay with M030 ROW springs. No advantage to getting the car lower and Porsche engineers got the math right. If you were running Hoosier A7s or Avon Slicks I would recommend more advanced struts like JRZ or Moton and a lot higher spring rate with a pro corner balance and setup. On street tires there is no benefit.
