Trading my ground control setup for a Spohn coilover setup. What should i do for rear springs? Where can i just get rear ones and what size or what not to have the car 1.5" or maybe a little more. Thanks

 

Why the switch? I can think of a few reasons why I like the ground control setup better.

IIRC, people were having problems with the shock bottoming out on the spohn setup on cars that weren't even that low.

 

Well the Spohn K member and A-Arms make it a PITA to make it go in. Plus a guy wanted to swap so... if i dont like it I'll just put normal springs back on it and call it a day. Wonder why the shock would bottom out...

 

Oh I see. I thought you were trading your rear weigh jacks for rear coilovers. Now I see you are only trading the front ones. The rear coilovers seem to have more issues that the front. Nevermind.

With that said I did not have any trouble installing GC weight jacks on my Spohn k-member and a-arms.

As for your original questions. SSS makes the pigtail rear springs in a variety of sizes and spring rates. I use a 10" spring along with the stock isolators and GC weight jacks. If you are not using the rear adjusters and want a 1.5" drop, I would try the 11" springs with the isolators.

Thanks exactly what i was looking for. What weight?

 

What are you running in the front? What are your goals for the car?

I run 850lb front 175lb rear. It works well and is livable on the street.

 

98% Stupidly overpowered street car 2% drag strip.

 

What rate will you be running in the front?

 

nevermind, wrong end
