on the sport is the bumpstop differnt from the non.I am installing a OEM sport on my car and dont have the bumpstop for the sport.

If you don't have access to the sport ones, you can simply trim about 10mm from your nonsport ones.

shouldnt he trim 20mm? he's got the 2005.5 sport suspension

Bumpstop length doesn't necessarily have a linear relationship with ride height.
The motion ratio of the suspension is not 1:1, so for every 10mm of wheel travel, the spring/shock does not move 10mm also. I believe it's 1:3, or 30%.

Keep in mind also that nonsport bumps are slightly softer in material versus the sport stops, so merely making the nonsport the same length as the sport isn't necessarily the right procedure either.

There's a LOT of flexibility with bumpstops, and by no means is there a fixed length or rule that everyone has to abide by for a certain ride height. Try different lengths and see how the ride feels, then adjust accordingly. Longer stops make for a more firm/harsh ride, shorter stops will soften the ride.
