Rear Coil Overs - How Low (Page 1/2)
michfiero1 OCT 21, 06:41 PM
Hi All, have looked around but haven't found the answer. Is there a "don't go lower than" recommendation for the rear when doing coil-overs (besides the obvious ground clearance issue)?

Many Thanks

If you plan on driving the car, you need to keep at least 2" of suspension travel in compression. Even then you will be on the strut bump stops all the time, so ride will be compromised.

What pound springs are you going to use? That will also play into how low you go with limited suspension travel.

Thanks for the responses so far. Let me flip the question around a bit. If I went with 12" springs, 325pds and lowered the rear 2 inches...what else do I have to worry about? Oh...this is an 86

Thanks again!

I ran 2"drop Eibachs on the rear of my 86 with no issues - 300# rating.

Thanks Joe...that was 2" drop springs or a coil over setup?

I think that would be a great combo honestly. The 12 inch springs will have less chance for coil bind as well. Not sure there would be much to worry about. There is a lot of room for 2" drop. I lowered mine a lot lower than that.

Mine is very low because it is a dedicated race car. Comfort or ride quiality are not my necesities, performance is.
My spring rates are #900 front and #700 rears. I know, too stiff. But it serves the purpose of my set up.
The front of the car is higher than the rear as you can see and that is to take away front grip and add it to the rear by
raising the front a bit and lowering the rear. I will tune it at the track, meantime it drives like a slot car with these sticky Toyos!

2" would be fine, as most people are in the 1" to 2" lowering range. Now going for 4", that is a little extreme.

Drop springs on KYB struts. Never saw a need for coilovers.....
