and a good graphic here, gotta scroll down for SAI

basically it is probably because the car is lowered changing the kingpin axis from where it was when stock. Nothing to fix with SAI or Cross SAI (difference of SAI from left-right)

Nothing to worry about though. Since there isn't anything you can do, because all the other numbers (caster, camber) look good and within spec.

 

+1 on engi, yet again.

You could theoretically run up to 4 or 5 degrees of camber before you drastically impact tire life. On my uncle's Reilly, we dial in about 2.5 - 3* before each race, depending on where we are. Then again, this is a purpose-built race car that goes through 2 sets of sticky tires in each 3 hour session.

But hey, not like you can actually dial that in on a stock setup.

Running 1 degree of toe will chew up your tires in less than half the time. On the scion, I run dead-ahead at the rear, and within factory specs at the front.

 

I would like to be able to quickly and easilly dial in a degree or so of toe on mine for autox events. Actually, you can mark everything properly and do it. But, as you said, it would be pretty harsh on tires on the street, not to mention it would handle in almost a scary fashion at highway speeds

 

how much does an alignment usually cost after you drop a tc. I just put trd springs on and was about to go in. all this talk about new bolts and stuff just got me wondering.

 

can range anywhere from 80-120+. some places do it by set price regardless if dropped on aftermarket stuff or not. some do a base price + price per axle if you have aftermarkets...mine was 110. 70 base + 20 for 2axles + 10 for aftermarket lowering + tax = ~110

 

look for a firestone complete auto care center near you:

they offer lifetime alignments for the price of 2 or 3 alignments (price varies for each shop)

sciontc_mich, thank you very much!

 

hey you're most welcome!

 

I dont align to oem specs (most autoxrs dont) so the firestone option is no good for me since shops like that align only to oem spec. I go to an alignment guy that charges less than half what other shops do for oem spec alignments and about 85 or so for a non oem alignment, depending on how much work it takes of course.

 

i smacked a curb going about 25 or more this florida black ice got me... and i ate up to bfg super sports in 3 days about 40 miles tops total... almost thought i had a tie rod bent all is well now
