Hi,
I've got a quick question. I'm looking at some second hand rims off a friend - they came off his ex-drift 180SX. The rim sizes are 17x8 (+32 offset) at the front and 18x9.5 (+38 offset) at the rear. Will these fit? I understand the stock offset is +35. Car is a JDM 1988 FC3S.

Thanks In Advance,
Ryan

assuming the bolt pattern's right then i'm pretty sure the answer is yes. what size tires are you looking at?

d0p3y

The bolt pattern is 114.3 multifit (4/5 stud) =]

Rear tyres are 235's (way too skinny for the rim, its drift-car style look) and the front rims currently have no tyres on there so I'm happy to listen to size reccomendations.

Sir Rupert Hobo

are you gonna drift it? i'm not familiar with drifting, so i wouldn't know what to tell you if it's just for drift. but in the front i would go no wider or taller then 235/40-17. you could put 225's on too.

that's what drifters do? put ultra skinny tires on the rear for less grip, right?

Running a smaller offset on a bigger rim up front may cause problems.

The widest you can go on the front without hitting suspension is 225 ( some people even have problems with those and have to run 215's... ). So youve already got that stacked against you. Before you buy the wheels, put a front one on and see how close it is. Youve already got two strikes against you with the bigger wheel and smaller offset...
It it comes down to it, you can always run spacers up front but I dont think thats "legal" in some sanctioning bodies/tracks...

Thanks for the help guys.

It won't be "drifted" as such until I am a better driver - I'm only 17. I don't want to be left with a messed up car and bills because I've become over confident with my driving style.
I can run spacers but I'd prefer not to. I'll try them on without spacers and see how I go.

Thanks again =)

Those would probably fit without a problem.

However, that's called "show car" look. If you want drifting rims... then you must not go above 16" for the FC. It doesn't matter what the width is, because the wider it is, you'll just need more skill to drift.

What matters is the diametre. Stick with 15" or 16"...

adamlewis

I think I have my offset backwards...I think the smaller offset will actually make the tire stick out more.


Sorry about that.

You should still throw one on there check though because it is a wider tire.

Good luck.

The stock offset on RX wheels is +40mm just so everyone knows

Would 15 inch rims with +15 and +27 rims fit?

Thanks.

Sir Rupert Hobo

nope

bighead

Yes.

Let me explain offset.

0 offset means that the flat part that bolts right up to the car's lugs is exactly in the CENTRE of the tire. Meaning that a tire with 7" width would have 3.5" on either side.

+40 means that the flat part that bolts up to the car's lugs is more towards the OUTSIDE. This means that more of the rim is inside the wheel-well, increasing chances of hitting suspension.

-10 means that the flat part is more towards the INSIDE. This means that more of the rim will be sticking out from under the fenders. Rims like this would have a lip so fat!!!

Sir Rupert Hobo

i seeeee, well. thanks for the explanation.. it sounded like it would totally NOT fit.

adamlewis

Yeah...thats what I was thinking earlier when I first replied. Then I remember I had it backwards and thats why I made my second reply.

d0p3y

Ahh good
This thread has been a nice insight into things, cleared it up a tonne. Thanks to those who replied!!

You may not like them but I thought I'd share the rims:


There's a picture of them on the car they came off. My car is a Gunmetal 1988 Savanna RX-7 13B Turbo =]

Better view of the rear rims

Project84

I'd get them.

does anyone else notice that the rims on that car are.... two different kinds? I hope you're getting all four of the back ones, cause those are sick. But cars with two different kinds of rims looks awful. Like youre buying your rims on the installment plan.

Below based on 7" +40:
I'd be concerned about the fronts (8" +32) It means the inner part of the rim will be .20" closer to the suspension, the outer .83 closer to the fender. I wouldn't want any rim closer than stock to the suspension. It's a problem putting wider tires on the stock rims, let alone moving a rim closer to the suspension. Maybe a spacer? The rears will be in 1.18", and out 1.34".
And by the way the +15 +27, depending on the width:
+15- 7" 1.18" farther away from suspension and also 1.18 clsoer to the fender.
+27- 7" .71" each
Now the 6"
+15- 6" inner 1.50" out and outer .47 out
+27- 6" inner 1" out and outer same location.
Keep in mind as said above, all are base on the factory 7" width rim +40 offset. If you have a 6" rim numbers must be changed for comparison.
If you haven't seen this before, give it a try. It sure helps:

Carefull. That kind of tire setup will help you break traction like crazy.
Otherwise, have fun, be safe.

A 17x8" wheel with a 32mm offset is the same as mustang wheels. I've heard of some people running 225-45-17's and 235-40-17's up front on those wheels without problems with rubbing fenders except at full lock while under load. This all depends on the actual tire width and diameter though, as it does vary between manufacturers, even if the size is the same. I'd be inclined to go for the 225-45-17's, and don't let them tell you can't go to 17's without huge consequences. As long as you size the diameter of the tire to be close to stock and the wheels are light enough there should be no problems. Good luck.
