enkei rpf1 and stock ride hight

i was thinking about getting some rpf1's but was unsure if they would fit my car, the are 17x8 and have a +35 offset, i read on here about someone needing spacers, would i need them at all? i am pretty sure my back would clear but im worried about the front. would i have to roll my fenders at all? anyone have experience with then on stock height? and i would like to know what is a good tire size.

And i noticed that it said 5x114. Is that the same as 5x114.3 or will they not work

Those should work fine. You can go with a lower offset if available. With 225s you won't need a fender roll. That bolt pattern is correct for the car.

If you needed a spacer in the front it would be to clear the brake calipers.

My battles are 17x9 +30 offset with a 235 tire. This was with a roll and a slight pull on stock suspension. I had 2-3mm clearance between the strut and the wheel.

After coilovers, I had to get 12mm spacers (extended studs necessary), and I have 1-2mm clearance between strut and wheel now.

I would go with 17x9+22 on RPF1s and I think you'd be better off. But LargeOrangeFont can correct me if I'm wrong. Keep this in mind if you do eventually plan to get coilovers.

Can't see how a 9" with a +30 would fit with the stock suspension as the combination moves the wheel in over 1/2", actually .59", then add a 235 tire??????
Geez, a stock 7" wheel +40 won't work with some 225 tires.


Reply to the OP question, with the stock wheel and GY 205's, you can't get a finger between the tire and suspension, so with your combo moving the wheel in 5/16", there will be some spacer needed.

I am running (up front) the RPF1 in 17X8 +35 offset, no spacers, cant remember the tire size of the top of my head (but I want to say that the tires are 235). At the time, I was running KYB AGX struts on ST springs, FD brake calipers. No issues with suspension/brake caliper clearance. The fender catches on the wheel during hard braking/turning.

With stock suspension (OEM) there's no clearance, but if there is aftermarket assemblies installed, there will be additional clearance, how much..............

Any aftermarket strut/spring will be the same size as factory.

HOWEVER: Coilovers (not Coilover sleeves like ground control) will offer more clearance due the assembles being smaller.

Just to clarify.

Sorry, but that's not correct. The '89TII we purchased new still has the OEM suspension and the top "plate" under the spring
seat has @ 9" diameter, while the '91 TII that has aftermarket struts, is only 3" in diameter.

I'm not sure if you are simply baffled or believe I am lying? I'm not sure if I have an inner fender picture from when this was my setup or not but I did mention there was very little clearance, but for months before I got coilovers, I ran 17x9 +30 with no spacers, a roll and slight pull, and had 2mm (?) clearance. Later I'll try to find the pictures.

Sorry, didn't mean to come off that way, but my statement was that it wouldn't fit with the stock suspension, meaning the factory struts, so it would make a big difference if the strut assembly was mentioned so as not to confuse the poster, and I guess this includes me. Maybe after 25/30 years I should assume that the stock OEM suspension is long gone and just ask the type/make of suspension components.
As I stated above, the OEM strut has a huge spring seat leaving minimal clearance while the aftermarkets units have various diameters depending on the manufacturer and would naturally afford more/wider wheel offsets along with various tire sizes.

I guess the bottom line is that anyone in question of a particular wheel width/offset, should just take the current clearance measurement, deduct 3/16", then use a wheel offset calculator to get the offset that will work. Now if larger tires are going to be installed, that would also need to be added to the equation.

Just because I want the correct information out there, I was on stock suspension and yes the 17x9+30 fit. It was very close to the spring but did not rub.

When I picked up stance coilovers, running absolutely very close to factory spec camber, I lost clearance. I had to buy 12mm spacers to now fit the wheels. I could raise the perch but that changes spring preload. I now have 1-2mm clearance again with spacers.

If that's the case, learned something new, so I surrender.
As the '89 TII is going in for paint next week it is currently sitting on '88 TII wheels with the OEM GY 205/55-16 and there is 5/8" (.625") between the tire and suspension. Now put a 30 offset wheel that will move the wheel in .59", then add a 235 tire that has @ 1 3/16" wider section width and you can see how, on paper, it's virtually impossible with the OEM components.

Guess I had better get a new calculator.
