Do 225/40 and 245/40 , roll your fenders and just get the BR series but get 10k rear springs (order the shorter ones) and your good. You may need (probably) some spacers.

alot of people want to know what offset fits their car and will it rub, tire sizes, blah blah blah. well every car is different and if you drop the car, increase camber etc. clearance will vary.

what i can tell you is if you don't plan on correcting your camber in anyway, your wheel specs will be slightly sunken in and spacers will be necessary for the look you're going for.

and i'll tell you now you will rub. why? b/c you're going to drop the car to the tire or rim and even if your flush enough to clear the fender, there's a spot of metal that is used to hold the rear bumper on that will basically rub on the bad bumps you get into.

but to answer your question its probably the bc-br 10/8k you want to go with... and maybe shorter springs b/c you wanna "slam" the car.

Can't wait to install mine! It's just trial and error with the rubbing issues. But definitely some modification is going to be needed when trying to go as low as possible.

If you just wanna slam the hell out of it, just go for the BR's. The other ones are kind of overkill for your needs.

I have the BR ones with the usual 10/8 rates with the standard length springs. Im tucking a little tire in the rear. The rears are nearly maxed for their lowering capacity though. If you want to go lower, then you're gonna need those shorter rear springs.



For me, the stance is perfect. Im actually rubbing in the front on some part in the fender wells... I have a cut going through the middle portion of my tire tread because of the rubbing I get when I corner hard. Its ok for now since I have plenty of tread for it to dig into...but when that tread goes away, its gonna be dangerous. See pic:



Ive got 19x9.5 19x10.5 +22 all around with 255/35 and 285/35 tires. I rub in the rear if i enter a steeper than usual driveway in the rear even though my fenders are rolled.

they only make 2 types BR and ER

they offer a lower version of the rear spring for those who want to really drop the hell out of the car (to the point where handling suffers). The standard springs will let you lower it about 2 inches

plan on rolling your fenders
