I will mount S-03 on stock rims with stock suspension at an alignment shop. What should be the alignment specs that I should tell the ppl at the shop due to the change of tire size?

Is there anything different or suggested to 18-4 to 18-6 on Helm's manual?

 

how would changing tires warrant different alignment settings? If your tire wear is screwy on your old tires, then have the settings checked.

 

Ray,
If you want an "autocross" setting, get 1/8th total toe out (1/16th each wheel) in the front and 0 toe in the rear. If the shop only does degrees, I am not sure. This will create a slightly bad wear pattern on your tires. Since the Bridgestones are expensive tires, maybe 0 toe all around might be best.

 

Dave, I will have a seperate set rims and tires for tracking purposes, these are just my street tires. I wonder if anyone here with 205/50-15 found a good long lasting specs for good wear....I know that plenty of guys here are running Azenis 205/50....

I wonder if all 0's will hurt performance in any ways?

Just align to the factory spec.

If your car was already properly aligned and you didn't experience any uneven tire wear or pulling to one side, then don't worry about changing the alignment.

 

I don't think changing the tires size to 205/50/15 will have much effect on the alignment.......I'm running 205/50/15 for about 6 months and I don't see anything wrong with the tires ( wear). I'm using Azenis (205) and for the past 6 months those Falken had been thru 6 track days and Autox ( too many times to count )
and I don't have any problem on tire wear !! ( FYI...I never do alignment on my car since I bought it from the dealer .....anyway I will do it for this race season )

 

Hmm...the urgency for alignment IS because my car pulls left and right on bouncy roads, and it shakes vigorously at 60-80mph. I think there is something wrong with the toe + that fact my RE010 have bold at the sidewalls, I've hit really bad pot holes... I've attempted an alignment couple months ago, but the tech said that my tires are so out of shape that an alignment is impossible.

 

Check your wheel !! Make sure they're not bend. A bend wheel(s) usually is the #1 cause of " shakes vigorously at speed "

 

Okay, then you need an alignment after you replace your tires. Just align to the factory spec though.

If your wheel is bent, they will find it when they mount and balance your new tires.

 

The R is very sensitive to toe. A toe out of 2mm is definitely noticeable, and is not very confidence inspiring. I usually have the car aligned every year, and each time it's off a little and I feel a difference...i.e better on-center feel, firmer, more communicative steering, etc.

If you have brand new tires, they will feel a little "loose" for the fist few hundred kilometers (or miles if you live on wrong side of the border . If you hit a pothole, it a good idea to have to car aligned. If the wheel is preventing an alignmnent, then that's probably what's causing the shakes at speed. A badly balanced tire can also cause the same symptoms.

 

Thanks guys. Bent rims are also the top suspect on my list of possible causes. I already went to a tire shop this morning and have all 4 rims put on balancing machines and I saw it with my own eyes that all rims are straight despite all the scratchs on it I have to make sure the rims are good before have the new tires on them.

Anyhow, the guy there told me the shaking is due to the very bad conditioned RE010s, I delay my plan of mounting/align tires to tomorrow, I'll let you guys know what the results are. So......I'll just point the Helm's manuel to the alignment guy and have him tune to specs? Do most alignment machines have the ITR factory spec database?
