I can't believe they didn't change that too!

Originally wanted RS+10 which is achievable with normal suspension parts, or at least as I'm lead to believe.

I've had RS height on a previous 993. Fantastic on track and awful on road.

With you being at 145mm front, you're almost exactly at the middle of the as-designed spec for the B8 + M033 springs.

With the B6XT (available from RL sponsor, Carnewal) You can safely drop another 10mm (but no more) and still be within "ROW sport" spec.

If I were you, I'd leave the car at ROW sport height. Remember, it's still 30mm below stock US height. If you really want to get it down to 134mm, I think you need to swap out those B8s for B6XTs.

Yes you are correct.

Whilst I needed to replace the shocks, I thought I'd lower the ride height. RS+10 is perfect in my eyes.

Knowing what I know now, I would have either chosen the H&R springs or the B6XT (although you get the floating spring issue with that.

All that said, the car handles great and this can't be ignored so I'm happy with what I've got, for now...

You won't get the floating spring issue with H&R springs
