The really important thing is how the car drove. My co-driver and i did 2 sessions a piece. He has driven the car at ever event that i have, so his feed back is just as valuable. The spacers had a noticeable increase in rear stability. It made it a little easier to carry speed into the corner without the rear wanting to chase you, so turn-in speeds may have been a little faster. What was more important was stability increased the "trust" in the car in the corner. As you may know, if you feel confident about the car, you will be able to drive it well.

Since I needed to remove the spacers for street use, i pulled them off before the last session. The rear end felt a little more unstable (duh) and if you gave the same inputs as before, the back end would tend to slide a little more. That may be good for autox, but not for the track. As easy as the are to take on and off, i may swap them on depending on the type of course. Tight courses may favor the spacers out, while the more open courses (like the one we were one) would be better with the rear spacers in.

All in all, i think they helped with the stability of the car. If i were not running such low offsets, i would continue to use them. If you have anthing more than a 35 mm offset, they are a no brainer, they easily fit and increase rear stability. The 10 mm should put the track in the front and rear dead even, while the 13 mm spacers may make the rear track greater than the front.

Great mod, track approved :)

I am looking for a little advice. So the wheels I have now on the Yaris were the very first mod I did and I must say, I didn't do my homework before buying. So I ended up getting 16x7" with 195/50-16 tires. After finding this kick-ass thread and doing more reading on the subject, I'm thinking about going back to 15x6.5" with 195/55-15, as recommended here

Now, I also have lowering springs (NF210) and shocks on my list, which is the next thing I had in mind, but I was wondering, would it make more sense to replace the wheels first and then get the springs and shocks or get the springs/shocks first?

do the suspension first, and then worry about wheels/tires after.

remember, the tire itself is the most important mod. size is less of an issue, whereas the tire compound itself is VERY important. don't go cheap on tires, and it'll reward you.

it's funny you mention those.. I'm thinking about upgrading my stock wheels to 17x7 Enkei RPF1 wheels with 215/40 star spec direzza's... I plan on keeping my stock steelies for winter use. The RPF1wheels are about the same weight as the the stock 15s, so I don't think weight will be an issue. This is my daily driver, so I am wondering if I'm going dangerously low profile and whether or not the ride will be too rough... Any one got any advice? Tamago?

sidewall is less important than the tire you choose. a 55 sidewall StarSpec is gonna be better than a 40sidewall (17inch) somethingelse..

sidewall is only detrimental when you're working with crappy tires like the Falken 512. the sidewalls are soft, and flex way too much in cornering loads.

that set up sounds fine to me. i prefer smaller tires mostly bc they are cheaper and i see alot of fast people use that set up. im not an engineer, so i just copy what works. im using 15x7's with a 195/55/15 dunlop. its a great set up. you can get the wheels for $120 a piece or less, and the tires are like $80 a piece. awesome deal, awesome set up... ive passed corvettes on hoosiers with this set up lol, seriously. cant wait to get the LSD installed and get some real race tires to try out nasa TT!

I was actually looking at some rims today and saw that if I went with 15x7" I'd have more to choose from as opposed to 15x6.5", as recommended by this thread. I want to go as light as I can for a reasonable price on the wheels. Maybe Enkei or something.

So how much can I deviate from "the letter of the law"? Are there any trade-offs? Most tires seem to fit a range (such as 5"-7" for instance), so that wouldn't affect the tire selection much. What would I sacrifice/risk with a 15x7 setup?

Tamago could you offer your opinion on these wheels:

http://www.good-win-racing.com/Mazda...t/21-1045.html

Things I need help choosing:
Tire sizes: for street use. going for good mix between weight / traction. have 205s now would like to go smaller.
Wheel size: 14s vs 15s. i want a good mix between weight / looks. i'm thinking 14s just might be too small since the car is not a miata after all.
Wheel width: 15x7? 15x7.5?

Relevant info:
Running the DF210s and Tokico blues.

If I had to take a stab in the dark i'd probably go with 15x7.5 with 195/50/15.
Any thoughts? More importantly is that Miata wheel even going to fit? I picked them because they're cheaper than hell, amazingly light, and from konig. Figured it was a great combo.
Thanks!

if you're going for looks, avoid 6.5" wide wheels. they simply don't fill the fenders very well. if you're looking to save weight, the wheel above is the one for you, very lightweight for the money, but you're sacrificing (IMO of course) looks FOR weight, i think that wheel looks awful hehe.

i use a 15x7 and it works great, i would use anywhere from a 195-225 on it and it will be fine. you wouldnt be sacrificing anything but a tiny bit of weight.
