Coilover length

[nazar]

I will be running 5" backspacing and zg flares.

 

I am about to get coilovers but dont know which size will work for sure. Will 5" backspacing clear a 10" 2.5 spring?

 

Some say you need 8" springs on wider than 9.5 wheels, but width of the wheel doesnt mater, its the backspacing.

 

Mine is 5" all around, will this clear 10" 2.5" springs? I rather run 10" springs to avoid coil bind as i wont be going drastically stiff, probably like 200 front/225 rear, does this sound decent for a street car with average track use?

 

Its an lt1/t56 with jtr setbacks 240z

5" will give you plenty of room if you use coil-overs. My 5" BS allows about 3/4" on the inside with 10" coils. Your spring rate will be fine as well, if you use a descent quality damper.

if i have sway bars front and rear, and my weight distribution is about 50/50 would it be ok to get 200lb rates all around?

Correction: the 5" BS will work fine, BUT I was wrong in saying that you'd have 3/4" to spare. I took a look today, and I've got about 1/4"+ clearance on the fronts, and a tad more on the rear.

 

I ran 200 lb/in springs for many years, and much later changed them to 230/265 front/rear. I like the later set-up better, but the 200s all the way around worked great. Search the archives on this matter. The fact (possibility) that the front and rear would (could) resonate between each other if they were the same weight was discussed. But I never (At least I was not aware of it) experienced this, and perhaps the dampers were responsible for that.
