GC's Has New Bread & Butter Kits

[Cronenberged]

New kit allows you to select spring rates which is a bonus for those familiar with flat ride.

I saw that, but you were always able to spec your spring rates with their basic "school" kit anyway. Not that an OTS Koni should be paired with too stiff of a spring anyways.

Also, you could always have created this "kit" yourself by buying the coilover conversion hardware and spring, then source your own yellow Konis or billys. Actually, I think that's cheaper with the pricing you can get on Konis/billys off ebay or some other vendor, esp with a discount coupon or whatever deals.

Doesn't seem like anything special. Better options out there for $1400 or just a little bit more.

Tbonem3 yea their other kit wasn't as affordable as this one is. It does create a one stop shop which might be easier for people to do who aren't as understanding of suspensions, i.e. myself.

Cobra I'm sure there is, but I haven't seen any that offer a spring selection.

You pick your springs with tck. I'd get tck s/a over gc if sticking with konis, but I'd use GC conversion kit and go with bilstein b6 over tck s/a konis.
