I Picked up a set of TC rims for ultra cheap to go on my 95 gt. I want to lower it with an eibach kit and was wondering a few things: spacers(sizes), tires(size), and shock choice.

I've read that 225/45/17 are recommended. Is that at stock ride height or would that work lowered too?

38mm spacer for rear brings it to 7mm. That too far? Should I get the 25mm? I like hellaflush style, but not necissary.
And 15mm for front? Im not sure. Getting rear fenders rolled, I gathered that much.

Lastly, what shock is recommended to use with the lowering springs?

I appreciate all help and input. Thank you.

I believe the best tire setup is 215/40/17 given that our 15in tires are 205/55/15. That implies keeping stock tire diameter. You can use anything you want, but 225/45/17 is bigger than stock, so your speedo won't read right.


If you're looking for stance, get coilovers. Otherwise, KYB, Koni Sport (yellows), etc. are good for up to a 1.5" drop.

What's the offset of these wheels?

I'm looking to lower it just purely for style. Most things on this car will be about looks. It's not going to be auto crossed or anything like that. Just a nice looking little car to toodle around in. Like my version of a 70 year olds corvette. Just want to know the right way to setup the scion rims to look nice fitting and get best ride I can. Tire size being stock is not a concern. And with the knowledge base here I'm sure I can achieve this in a more cost effective manner than trial and error.

Main thought is I don't want to be rubbing inside fender wells and ruining panels or tires. The eibachs drop it 1.5" and I put spacers on to give it a nicer stance, what size rubber would be advisable with what size spacers? Thanks to all.

45mm offset.

225/45/17 with +45 offset on 17x7 wheels won't rub.

You can actually measure how much space you have left at the fender with a tape measure... you should do that. Measure from the tire to different places in the fender (from the highest point of the fender towards the front of the car on the rears, and backwards on the fronts.

It'll be close to the strut on the inside though wont it?

Will it be close to the strut if I have a spacer/adaptor installed. That'll push it away from the strut also, correct? Then I just don't know about making contact with the fender itself.

I know I read a thread on here where someone said to get 225/45/17 on the scion rims and you'd be happy you did. I just don't know what other mods he was running.(lowering and spacers)

Most likely it will, yes, but they won't rub on the fender, which is what I meant... so some spacers should take care of that. I think stock GT wheels are 15x6 +38?

Found that site that you should check out. The numbers are specifically for 6thgen.

Cool. Sadly I'm still not totally understanding it. Offset and backspacing are things I don't understand fully. I guess I might just put sOme tires on the rims, put um on the car and measure.

Thanks for help.

Okay, so, let me inject a bit o' experience here: I bought my tC wheels with 215/45/17, and have now switched to 225/45. I like the extra "beef" on the sidewall, but in turn, the tire is heavier on an already heavy wheel, and the bit of extra sidewall actually flexes, really taking away a bit of sensitivity and adding slight heft. It makes for a nice ride, but not very efficient - I imagine lots of drag as well. The ST doesn't need the extra rubber anyway as far as power goes, although the extra grip is nice. No issues with rubbing, lowered one-and-a-half inches.

My next try will be 215/40, which will hopefully improve on everything except for ride quality.

My other recommendation is to figure out the tire first and then mount everything, then decide on a spacer. It'll be easier to do once the wheels are actually on the car. As far as a lowering solution, the stickies will provide more concise advice than me.

My recommendation would be to use 215/40 to keep stock diameter (keep stock handling qualities) or 205/50 for a softer ride.

Remember you can always run staggered tires if you're looking for grip, as well. Wider tread and shorter sidewall on front, and the equivalent tire with less tread and more sidewall on the rear. Staggered tires don't let you rotate them though, so I would just go 215/40/17 if you want to keep stock handling. You'll lose ride quality but there's pain in beauty, always.

Here is my car on 225-45 tires with 15mm HR spacers with TC rims. Its lowered on eibach sportlines, and the shocks are due for a change.

^ Indeed, looks a bit droopy compared to mine. 'Tis lower though.

Thank you for the pictures, which officially kills my plan to space the wheels out a bit. Man that offset sucks. I'm need new wheels...

I think lagos's car looks nice. I just bought a set of tires for the Tc rims I have, 225/45/17... price was right. SO do you think 15mm spacers all around is best or is that just spacing the rear? Thanks!

205/50 is stupid big for 17" wheels. You'll be driving a monster truck and the engine will cry.

If you're running 17", to fit OE spec you'd have to do 195/45/R17, or 205/40/R17. I'm going to be running either a 205/40/R17 on my Enkei's (same fitment as a TC rim) or 215/40/R17 because it overlaps the rim a bit and will protect it more from potholes around here.

Factory GT rims are 205/55/R15 with a +45 offset. Stock TC rims are 215/45/R17 +45. Running a wider and larger tire adds grip and comfort but increases sidewall flex and "wobble." If you're into bombing corners, stick with OEM sizing or just slightly larger (like a 205/40/R17 or 215/40/R17)


EDIT:
Size up general rules:

Optional Tire Sizes


Plus Zero 185/60-15

Plus One 185/55-16
205/50-16

Plus Two 195/45-17



I guess the question I have for those that have run 215/45's is; have you noticed any loss of power or pickup?
