Questions about TRD springs and 17x9 wheels

[Vincent Nguyen]

Hi all, this is my first post and I am a new member since I bought my FRS few weeks ago.
My car is a pre-owned, it is lower on TRD spring, has a sway bar and front end links. I am thinking about getting Enkei RPF1 17x9. So my questions are:
1. Would I be able to fit that wheel size? (I am getting wheels first meanwhile saving up for a really good set of coilovers)
2. What extras parts should I buy to get custom wheel alignment? And what would be a good alignment spec for that set up?
3. What is a good choice of tires for that set up?
It is really tough for me to buy wheels and coilovers at once. That's why I am thinking about buying wheels first since the tires are almost out. I would love to have a set up that can handle spirited driving and track.I am sorry for asking too many questions, any response will be appreciated. Thank you!

1) You should be able to fit that wheel. Might be a little tight on clearance between tire and spring perch, but should clear.

2) If your goal is get a custom wheel alignment, I'd suggest lower control arms for the rear and camber bolts for the front.

As for alignment, I'd suggest max out your camber bolts (most negative) and for the rear around -1 to -1.5 degrees depending on how much you drive on the freeway. If you drive on the freeway a lot, you'd want the camber closer to -1.

As for toe, a little negative in the front will give you quicker turn in, but too much negative toe will make the car twitchy at speed. In the rear, you can go for 0 to a little positive. Positive toe will make the car more stable in a straight line.

3) What are you looking for in your tires? Dry grip, long lasting, cheap, etc.

3. I am looking for dry grip tires but last at least 2-3 years. I would spend up to $180/tire
2. How much toe for front and rear should I have without destroying tires quickly and be stable at slow and high speed?

You need +35 offset for a spring setup. +45 won't fit without coilovers.
2-3 years? I suggest looking at tread wear ratings of 300+. I like the hankook v12 or continental dw. Lots of people like michelin pilot super sport.

Toe-in makes tire wear faster and also makes it more stable. It is a trade off.
Most recommend 0 toe or slight toe in the front and slight toe in in the rear or close to zero. How much is slight? Everyone is different, start near stock and go towards zero.

Thanks swarb, you guys are super helpful. I'm still a noob, need to learn a lot more.

I just saw that image in another thread, those wheels... they aren't TS9's are they? How tight is the fitment? And how do you like the ride with the TRD springs?
