(HELP) 17x9 RPF1 meaty fitment
 

If you're here to light me up about a duplicate post, just click away now.

I need some help!

After months searching I found the wheels I want to run on my 2013 BRZ.

I want to run 17x9 RPF1's with a 245/40/17 tire

I currently have Eibach Pro-Kit lowering springs which drop my car 1" in the front and 1" in the rear.

What offset would I need to be able to run this setup with 0 chance of rubbing? Would I have to ditch the springs? I would like to start getting into track days.

Going for this look (this guy is running 17x9 +35 with a 245/40/17 but I'm not sure if he has lowering springs or not. Nor am I sure whether his setup rubs. It also looks like his wheels stick out pretty far.)

+35 is your safest available bet. 17x9 +35 with 235/40 tires barely cleared my stock springs though.

245 would be worse obviously.

I wonder how this guy has done it, then..

I really like your setup as well.

+35 is the way to go on this setup. Can clear BBK and you can dial in some camber without rubbing on stock struts.

And yes, I'll still flame you just a tiny bit, this EXACT question is posed about 150 times on the rpf1 wheel directory. It's a sticky, and there's pages upon pages of pictures, examples on stock suspension, lowering springs, and coilovers.

The bead measurement of the tire can depend slightly on the manufacturer. My NT01's are 235s but the sidewall comes out pretty square. 245/40 is the tire size of choice for most tires, though ive seen 245/45 MPSS work just fine on everything stock. I'm dropped on TRD springs on stock struts. I drive in canyons and track frequently and have no trouble with rubbing.

You can run 245/40R17s on 17x9et35s no problem with lowering springs. I did it for some time while autocrossing before I put coilovers on my car. If you run the 17x9et45s it may be a very close fit depending on how much front camber you run.

Here's some shots of mine on springs and with the et35s:

Awesome! Thank you so much.

I think I'm going to go with +35mm because I will be running stock camber.

thanks

Btw you no longer have "stock" camber if you're lowered on eibach springs.

Thanks.

But yeah, when mine were mounted up I was barely able to run my hand between the spring and the tire. It was too close for my comfort.

Coilovers in and it was just fine

So I have 17x9 +35mm Enkie RPF1's in my cart with 245/40/17 Pilot Super Sports to wrap them in my cart. My car is lowered 1"

I've someone reassure me it will fit & someone tell me it won't fit without coils...

Anyone want to chime in before I buy a setup that doesn't fit?

Maybe I missed the part about you being lowered but are the springs in the car now, smaller in circumference than the stock ones were?

If significantly, then you should be ok.

Coils are just much smaller around than the stock springs are.

I'm not sure if they are a smaller diameter. I doubt they're any larger.

Their Eibach Pro-Kit springs AKA TRD Springs

It's the spring perch on the strut that you'll rub, not the coil itself. And no, not any bigger in diameter.

I had same wheels, same springs, same tires, and it fit fine. No rubing. Plus camber was set at -1.2 front and -1.5 rear.

There you have it

For autox last year I ran a set of RPF1's 17x9 +35 with 255/40/17 Hankook RS3 lowered with swift spec r springs. I would only rub at full lock while reversing out of my driveway. It was rubbing on the inside frame not the shock. Otherwise no rub and no issues. Going with a set of 245/40/17 will be fine.

I too want to get 17x9 wheels on my eibach pro kit. Sadly they only offer it in +42. Anyone know if I'll have any problems with rubbing or anything

+42 would bring the wheel in more than +35. You'd worry about rubbing on the springs over the fender in that case.

Fortunately though, you could use some spacers to move the wheels out a bit. Shouldnt need more than 10mm.

Id imagine this combo is probably described on here somewhere.

You can find 17x9 +35 here.

I've been looking for this answer for like weeks! I have the same exact wheel and tire set up and thought about running the same springs but with bilstein shocks. How much camber were you running up front and how were you able to achieve it? Are you still running this set up? And how satisfied are you with it?

I was running around -2 degrees just using camber bolts. It worked well for that season but just wasn't as competitive. I would imagine with bilstein shocks it would be pretty awesome.

I moved up to a set of Fortune Auto 500's that I got cheap. Spent a year on those and had them rebuilt and upgraded to 510's.

So with -2 up front there was no rub at all on the spring or spring perch? Would you also happen to have a picture of your car in this set up that isn't an action photo? Thanks!

Im running 235/45 on 17x9 35 RPF1s right now, with a -2 camber up front. it close to the struts atm, if i decide to run a 245s i think it might rub slightly on the struts. you can always throw on a 3mm spacer which is "safe" to run on oem studs if you experiencing any rubbing.

Here are a few that are not action pics. Looking up the camber bolts it was probably closer to -1.7 than -2.

@Shneegle thanks, that looks great! So this was just springs, camber bolts, and adjustable rear LCAs?

I recently moved and have to raise my car a bit, I am on HSD coils and they have unfortunately seized up hard.

My cheapest option is to put the stock struts in, but I do want that slight drop so Ill be getting the trd lowering springs.

I am running rpf1 17x9 +35 on 245/40/17 mpss. I am seeing that a couple of the guys here have that set up and it works fine with the 1" drop from the trd lowering springs.

Just to confirm before i make the purchase are the camber bolts necessary for the fitment ? Or was that installed because you wanted that slight tuck in for the wheels?

Thanks!

Thanks, and correct. It has been changed since then but at the time of those photos that's what it was.

Autox/track is why I had them in. I wanted closer to -3 degree of camber in the front but without top-hats you can get that. The camber was bringing the wheel/tires closer to the shock/spring. No the bolts are not necessary for the fitment. The tops of the tires/wheel might poke a little more tho.

Yeah they do poke a bit, I had the wheels on stock for a bit before getting the HSDs. But I can live with that if I can get into my garage haha.

Thanks for the confirmation dude.

u'll be fine.. i have 17x9 57DR +38 lowered on TRD springs with -1.7 camber up front and i pretty close to the perch... with +35, u'll have tons of space

I've tracked with 245/40/17 on RPF1 17x9 +35 and got zero rubbing at all.

Pic below shows the wheel/coilover under heavy compression.

Hows the performance on 17 9 with 245/40 tires?
It got slower?
