Anyone have first hand experience running Advanced Design Shocks made by Ground Control? "The Beast" came with coil over shocks on all 4 corners from the above company. They are 2 way adjustable, N2 filled. Since they have been sitting for several years and do not have any N2 left in them, I was going to have Ground Control give them a tune up. The tune up charge is $50 per strut.

How are these shocks in comparison to Re-valved Bils, Koni adjustables, and any other shock out there. Do I need to budget for new shocks as well?

Thanks,

Bill P.

Bill, call Tony C.
He rebuilds and revalves these shocks...

I've got them on my 240Z autoX car. Works for me. They were the best option at the time since I couldn't afford Penskes, etc...
Fully rebuildable for not a lot of $, good tunability and performance.
My 2cents...

Thanks Michael,

That's the kind of feedback I'm looking for.

Happy to be of some assistance.
When I get a clutch in my V8 car again perhaps I'll get a chance to be mobile and actually meet some of the other bay area nut-jobs!
I'd love to check out your projects if you're game one of these days.
