I can provide that info for Cups and RSRs but not the street cars.

2000>Cup:
front 240 n/mm + 60n/mm helper, 5 pos 26.8mm rollbar
rear 260 n/mm + 60n/mm helper, 3 pos 20.7mm rollbar

2005> RSR:
front 4 step adj. 282 n/mm 293 n/mm, 317 n/mm, 345 n/mm rollbars infinitely adj. from the cockpit
rear 4 step adj. 282 n/mm 293 n/mm, 317 n/mm, 345 n/mm , opt 317 n/mm 333 n/mm, 352 n/mm, 375 n/mm

You can't directly compare these rates to 911 rates due to geometry differences

Bill,

That is cool info.

The RS numbers look a little funny with a very large split ???

Must run a really big front sway or no rear to make it work.

Thx.

285 / 385 was referenced by someone on another forum but do not know if 996 or 997 GT3 or if credible.

Bill I am guessing the RS 993 numbers must be 346/457???

All the #s I posted come from factory documents, again don't read too much into these #s the geometry of the 911/964/993/996(7) suspensions is very different, to compare you would want to know the wheel rates.

GT2evo uses adjustable rate springs like the 997RS all are N/mm, all use 60 n/mm tenders
f 270, 287, 305, 320
r 296, 312, 330, 350 opt1 235, 252, 269, 286 opt2 284, 298, 314, 333
