I think they're pretty good. :) Our T2s are used by track day people, time attack, and wheel to wheel racing.
KW North America does our rebuilds (and they build the coilovers to our specs).
Easy to reach us almost 7 days a week for tech support and service.

Feel free to PM me if you have questions.

Do you have any specs on the Reinhardts? Shock dynos?

I asked CSG Mike on coilovers.

As far as Reinhart, no info on them and they took down their website and only a select few are currently using them in GridLife.

Give Touge Factory a call about Reinharte... I think they make them in house.(could be wrong though)

I would go with Ground Control in my opinion. been running them for almost 4 years now and have been great at the track with 440in/lbs all around. and it drives nicely on the street too.
