I've been running a Roche P12 USA Spec for a few months and picked up a CK25.

The CK25 with stock setup except for front brace and .45 side springs feels AMAZING. The car just carries so much more corner speed.

Never broke a single part on the Roche even when I ran a boosted 6.5T but did manage to taco a chassis.

If I could do it again I would have started with the CK25...
