Autocross 818S spring size

[TouchStone]

Taking hard turns during an autocross race has my body kit dragging on the ground. I currently have the stock S springs without a sway bar. What is the the best way to fix this? Can I just adjust the ride height or is it better to get larger springs? Anyone know what size springs would be best?

You can increase the preload or just get stiffer springs. The kits use standard 2.5" x 8" springs, 7" will also work. We're running 350s in front and 550s in the back with no issues so far. (edit, where was my head?! HA)

Do you happen to have a link or product#?

Or does anyone have a pair of their old 500# rear springs I could buy?

Are you sure they're 3" springs? From what I recall, I ordered 8" x 2.5" (ID).

[TouchStone]

I just checked mine are 2.5" ID

Go on ground control suspension website, you can order pretty much any spring size and rate you want. I'm running 350 F 500 R.

Eibach 2.5" x 8" is what you need. Cheap and easy,

[TouchStone]

Yes the 2.5" is key, looking for 3" x 8" springs are much harder to find.
