Getting an alignment in a few days - input appreciated
I know I may get flamed from another alignment thread but after seeing my rear tires disappear in front of my eyes in the last couple thousand miles I would appreciate any input from you guys.
I installed eibach springs and a rear camber kit (new front tires too) about 3000 miles ago and immediately got an alignment. I went back about 500 miles later to get another alignment after the springs settled. To me it looks like the springs have settled some more since then so I'm going in on Tuesday to get another alignment. Thing is I need new rears now too. Yoko Advan Sports (295/35-18) lasted about 8k. I know I drive a sports car and I know my driving style has something to do with it but I drive 60 miles all highway everyday and I was surprised how quickly these tires died over the last couple thousand miles. They didn't look too bad when I put the springs on. Last alignment: -1.4 front camber 0.08 front toe-in -1.8 rear camber 0.15 rear toe-in All of the above was at the alignment guys recommendation. When I was in ordering new rear tires (Toyo T1-R, 295/35-18) I told him I wanted to take out some rear camber to about 1.4/1.5 and although he said ok he didn't seem to want to go against what the computer (Hunter) was telling him. I asked about toe settings and he wants to leave them right in the middle of spec. What do you guys think? The front tires look great. Nothing concerning after the first 3k miles. One last thing. The Yokos had a treadwear rating of 180 while the Toyos are 280 so hopefully that helps them last a little longer as well. Otherwise I'll be buying new tires 2-3 times a year.

Where is the wear on your rear tires, middle, inside, outside? Your alignment is within spec. Maybe since your last alignment, nuts came loose? I have -1.9 and .06 for the rears and have normal wear after 2k miles. Tires can last up to 20k. Your springs shouldn't take more than a few days to settle, the rubber parts may keep compressing for a week.

Wear is worse in the middle, least on the outside. Inside is halfway between the two.

???? If the wear is worse in the middle, than that seems like you are running too much air pressure. Have your alignment done again with a little less camber in the rear like you stated, and keep in eye on you air pressure. Maybe even run nitrogen instead of air, it might help keep your pressure and rear tire wear a little more consistent. Also going with the higher tread wear rated (harder) Toyo's like you stated should help with tire longevity. Good luck |

I always set them to 36 psi cold all around, maybe that's too much for the rear? I'll try a different gauge and see if the one I've been using is off. The only place around here that does nitrogen is costco, I'll swing by there when I get the new tires on and find out how much they're selling it for
Big thanks to you guys for the help

Its the commute + rear toe that I think is killing your tires. 60 miles at highway speeds every day does a number on an aggressive setup like yours. I would set to 0 and ease up on the camber. Also...I would have more negative camber in the front that in the rear...

I'm trying to see if I'm getting a good deal or just bs: I was quoted $400-$600 for the install & $300 for the allignment from a local place. Does that sound about right or it just alil too much? I have a set of KW V3's coming at the end of the week and want the best deal.

An alignment should cost 100 - 150. If you're getting corner balance, then 300.

Our coilover installs start at $200 and $100-$150 for a four wheel laser alignment. We also can corner balancing for an additional $250 |

I agree, zero out the toe will help the wear rate. Back the rear camber down to 1.4 given the number of commuting miles you do.

What other places or shops do you guys think I should go to to get my KWs V3s installed, im trying to get a good deal but $700-$900 on a suspension install + allignment kinda makes me sick to think about, lol I feel like im getting ripped off in a way.

going to agree with a couple posters... neutral toe, less aggressive camber... maybe -0.8 / -0.2 front/rear... plus or minus a couple tenths you won't know the diff... you'll feel a bigger difference on toe - even an eighth... typical alignment shop is going to want to go with factory spec... give neutral toe a try and see what you think... might "dart" around too much for you, if so have them dial in front an eighth
having such a big treadware rating difference front and rear is going to be noticeable... depending on how aggressive you drive, be prepared for oversteer if/when you drive at the limit |
