Lower front more than the rear on coilovers? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

stlgrym3 · 05-31-2018, 10:18 AM

When I got my Apexi coilovers I lowered about 1.5 inches front and rear. However, because of the higher wheel arch up front the wheel gaps in the front are quite large compare to the rear, I’m on 17” wheels by the way. Is it okay to lower the front even more to even out the wheel gaps between front and rear? Wouldn’t the car be slanted if I do that? Is it common practice to lower front more than rear?

Something is wrong if you're seeing a big difference front-to-rear. There shouldn't be a big discrepancy if it was evenly lowered.

What I meant was the front vs rear wheel gaps visually. Don’t the front wheel arch higher than the rear begin with?

The difference is only supposed to be about an 1/8th inch. I would double check your install.

Stock Ride Height

If you get the front and rear even at the pinch welds, the rear wheel arch should measure 1/8" lower than the fronts. It sounds weird but it's just the way they're designed on this car. I guess if you wanted them to look dead even then you'd actually need a 1/8" rake measuring at the pinch welds. Keep in mind fuel level and trunk junk can make a difference on this to.

^^ What those two said. The difference at stock height is 1/8" (3mm), which you won't see without carefully measuring. I personally set my V3's to be even all around when measured fender to ground, so technically mine is lowered an additional 3mm up front.

I wonder how lowering more front will affect weight distribution, downforce/lift bias, handling. Or that small of difference shouldn't be noticeable?

I think we r talking about different things. I was referring to the wheel gaps between the front and rear wheel arch. By default front wheel arch always appears higher than the rear, so when lowering both sides evenly, the wheel gap difference is still there.

I have Tein Flex A Coilovers installed recently, I have the opposite problem. My front is lower than the rear. But according to the people who installed it, it's set to "Tein Factory Recommendations". My front camber is roughly -1.5 and rear camber is roughly -2 degree.

I'm pretty sure the car was designed with a bit of rake.

Yes to allow for max travel without hitting the shock against the CV joint.

Also max downforce yo

In a bolt on street car that gets tracked, I'd say not that much. My lock rings backed off on my ride height adjustment and I was 16mm on the right front, and 12mm lower on the left front then the rear. I noticed the car was a little skittish over a crest under power, otherwise I didn't notice much else besides a little more rubbing then normal. I just reset it to where I previously was which is about 6-7mm lower in the front then rear. I guess potentially you can improve the effect of a rear diffuser with some positive rake. I doubt it is that much in a street car though.

For improving rear diffuser angle/effect i guess car needs to be much lower and with side skirts to lessen air getting in from sides under body. So yes, at stock height probably downforce will not be changed much.
