You can use Koni FSD.

IIRC the M030 lowers the front ~3/4" and the rear 1/2" from stock. The HDs could work but M030 is the sport option so the Bilstein Sports would be the preferred choice.

Thanks for the input! So koni FSD or Bilstein Sports, either have an advantage?

I installed the Koni FSDs on my 98 and I recommend them highly. Some input in the attached thread.

@911Monty What should I look for as far as damage from bottoming out? There was no leakage when I swapped the H&R for stock springs. They look brand new. I would think damage would show some leakage from the top seals?

Mike, You're fine. Your shocks were designed for the full travel of the stock suspension. The damage I referred to would be internal. Can happen on slammed cars using non stock components that have significantly altered suspension travel causing the shocks piston rod and valve to be the limiter on full compression. Guess I only brought up to emphasize the suspension should be thought out as a system designed for an intended purpose instead of just mix and match parts, especially now that these cars are so cheap that we are seeing modifiers going for look instead of purpose.

I just installed H&R lowering springs 20779's along with Bilstein B8's. Car is slammed problem is with the change in geometry I need to install adjustable rear toe control arms to get the proper alignment. Has anyone else had this issue? Also what type of outer tie rods did you use? I have Meghan racing but again there is not enough adjustment for proper alignment.

Looks great but I am more amazed by how little you paid for installation. Here in MA they wanted $800 (Not even sure that included alignment, likely not). I ended up doing myself. Most sleepless month ever.

Beautiful car by the way.

Oh, I have H&R Springs with Bilstein HD's. No issues what so ever. I had just the HD's but it wasn't lowered without the springs. No other fancy bits. My friend has H&R with Sport. It is very low. Probably 1/2 lower with sport. I'll post mine with H&R and HDs.
