First of sorry if this is the wrong section but it is related to suspension lol. Anyways Ive been doing some research and it really hasn't gotten me anywhere. I just picked up my second set of rpf1's in the same specs as my previous set up. 17x9 +45 255/40/17 all around. Now before i put them on im going to be raising my car a little bit and re doing my alignment. Im just looking to add a little more negative camber in the front and even out the camber in the rear. The car is my dd and does not get tracked but i do take it for spirited drives often. Just looking for some advice on my current specs and the specs id like to change to.

Current specs

Front toe: 0*
Front camber: -1.3*
Front caster: 6.6* (Im worried that this is excessive)

Rear toe: .50*
LR camber: -3.2*
RR camber: -2.9*

What i was aiming for when i redo my alignment was keeping front and rear toe the same but changing my front camber to -1.5* and making my rear camber an even -3.0*

Any advice or insight is appreciated.

 

You really need more front camber to help with fender clearance and handling would benefit as well. I would aim for at least -2. I have mine maxed out at -2.8 and still worry about the front tires destroying my fenders. 245/40 is really a better choice for the front but my wheels came with tires already, same specs as yours.

Rear camber seems a little excessive and isn't needed for rear clearance. Also, that is a lot of toe in and is going to wear through tires extremely quick. I am at -2.5 rear camber and 0.22 TOTAL toe.

In summary: I would run more negative camber front, less camber rear, and less toe in rear. Caster shouldn't be an issue.

 

I concur. Safe to say, max out the front negative camber, and max out the rear camber in the positive direction. Cut your current rear toe in half.

 

Thanks for the input guys, the only thing I'm still somewhat confused about is my rear toe because I have it set dead in the middle of the specs from my alignment machine. So when I redo it i should be aiming for .25* total rear toe?

 

Is this an ap1 or ap2? And just to verify, you have 0.5 degrees total toe at the rear? That's actually right about where it should be for an ap1, but roughly double the ap2 spec.

I would also bring the rear camber down a lot to something like 2.2ish. You'll just wear your tires excessively on the street, unless you do a lot of very hard cornering.

 

Sorry forgot to mention it is an ap1 MY00. Yes currently my rear toe is .50, that's why I was still confused because like I stated above its dead in the center of what the alignment machine suggests.

So now after reading all this i should be ok with keeping my front and rear toe where it's at and going to -2.0 front camber and bringing the rear to about -2.5. I do take the occasional hard corner and on ramps but I'm not out blasting through the streets on my my daily commute.

 

I'd probably want a little less total toe. The high amount of positive toe keeps the rear of the car more stable and probably evens out the tire wear a little bit when coupled with -2.5 deg camber. But...it will be very fast wear.

I'm going to use 0.14 degrees per side on my AP1. That trigs out to about 0.06 (1/16") per side with 255/40/17 tires.


Stock AP1 specs are close to 1/8" per side!

 

Ok thanks for all the input guys, I'm going to keep reading up on it and hopefully I can get it all dialed later this week.

 

I would also agree for less toe. I run .16 deg toe total (.08 each side). Remember you want an even number because you'll be dividing that total by two. For just street use -2.0-2.2 front would be a good fit. Just be sure to tell the guy to max the caster out, you'll have a little less after raising the car to play with.

I cant recommend a rear camber setting though without knowing what you have done with the sways. Since you're square, I assume you've upgraded at least the front.

 

I'm doing the alignment myself at my job. And my sway bars are stock front and rear. I've ran this exact set up in the past but wasn't completely happy with my last alignment that's why I'm trying to just get it dialed in where I want.
