They should fit, IIRC the FD hub bore is around 61mm so that is about 1/2 an inch bigger. Also, you'd want to run 255/35 on those 18s.

Great!

Thanks for the tip on the tire sizing. I'm a total goof when it comes to wheel's, but is there any adverse effect having the bore bigger?

Will this fit (specifically worried about front outer fender)?

18x9.5" 44et on all 4 corners with 285/35/18 on GC coilovers with 550/450 springs.

According to the excel spreadsheet for FD sizing it will interfere 0.41" into the front fender. Not 100% sure what the assume camber is on that spreadsheet. Perhaps the clearance could be dialed in with negative camber (I run -2.5 to -3 degrees). Anyone with similar setup car to comment?

Quick question:

When I used the calculator to verify if 18 x 8.5 +25 front
and 18x 9.5 +25 rear would fit it tells me like -.25 clearance. This is without rolling fenders. So if fender inside lip is rolled these would fit? Or maybe someone is using these sizes?

Would these fit?

Thanks,

Turned out great!

Went with:
245/40/18 F
275/35/18 R

Im going to add a 5mm spacer for up front and a 10mm spacer in the rear.

Hi, Im going to be buying some aftermarket rims and tires for my FD, and my question is... Will a 245/40/17 tire fit for the fronts and rears fit without rubbing, or having to roll the fenders?

BTW my car has the Tokico Illumina adjustable shocks, and eibach 1'' lowering springs. The rims I want, would be a 17X9'' with a +24 offset. Any help would be appreciated.

The +24 offset is the problem. If you don't want to rub stick to +45 on a 17 x 9 rim. If you want to risk it, its your money.

Remember 25mm = 1 inch
+24 = 24mm = almost 1 inch
+45 = 45mm = almost 2 inches or about 1.75"
+50 = 50mm = 2 inches = the stock FD offset

I knew that 24 offset would be a problem... I'll check out some other rims, but just wondering, what kind of body modifications are we talking about to get the 24 offset to fit? would it just be rolling the fenders, or would the rim also hit the shocks, calipers, inner fender lining, and require more extensive body modifications?

Think about it a bit. A +24 offset means they stick outward another inch. So it shouldn't be rubbing on suspension components right? It will be rubbing on the fender.

I occasionally rub with a 17x9 +45 on 255/40/17 and rolled fenders. With a +24 offset rim, the tires and rims would be sticking out beyond the fender's sheet metal.

Im looking for a quality aftermarket black rim with a large outer polished/chrome lip. The size I want is 17X7.5-17X9

This is the look im going for




This rim is quite affordable, but its hard to find another rim similar to this one for a reason price <$1000. If anybody has any ideas please send me a PM. BTW, thanks Gracer7-rx7 for the info

You want at least an 8" wide front rim. The stockers are 16" x 8". Don't downgrade. You can also search on posts from Goodfella on rim sizes that work if you can't figure it out in the spreadsheet.

Tire Rack list some good fitting options. Alternatively contact AUTORND here on the forum. He can hook you up with rims that fit properly at a fair price (and deliver good service).

Ya you're right, downgrading to 7.5'' rim is a bad idea. I actually have been researching all day long ( it's my day off ) , and have found some different wheels with the exact same look I want. They're 17X8.5'' 19.5 lbs each, black with a larger outer chrome lip, built from cast Iron, and the price is reasonable.

They have several different offsets... would a 245/40/17'' tire with an offset of +40 and 8.5'' rims work without body modifications?

They also have +45 and +48 offsets which are better, but just wondering worst case scenario they arn't in stock, if the +40 would work

Thanks gracer for that, it's greatly appreciated.

in regards to wheels great fitment always will come down to your budget. Based on your budget you may or may not get your most ideal fitment.

in this case the style seems to be more important that maximum width or wheel weight. This should be a pretty easy setup to find on the net based on some criteria of course.

Rules of thumb:

always get at least your stock width or wider. 8" or wider as mentioned above.
if you go taller than stock, then you should go wider than stock. That's my thumb. lol. so at least 8.5" wide.

1. Do you want to rotate your wheels/tires?
2. What size tire do you want to run?

Once you've isolated these items and chosen maybe 5 wheels you like I can pick the one of best fitment. I might not offer the wheels you choose but I'd be happy to advise your choice.

I personally don't know. Rishie does this all day long though so he is a great person to work with.

Here is info on fitment from Goodfella. His setup looks great running a 17x8.5 +44 with 245s.

The rims I'm thinking about getting in 17X8.5'' (x4) are Rota D2's. I think 19.5 lbs per wheel is much better then the Motegi Touge at 23.5 lbs per rim



I found this thread on here about these rims....

https://www.rx7club.com/suspension-wheels-tires-brakes-20/rota-d2s-work-meister-s1-knock-offs-586609/

I know that they are a replica of Work Meisters, and im ok with that, because im not gonna spend $3,000 on forged wheels I have to special order from Japan for a daily driver.

Plus Rotas are better then Drag wheels. I would be embarrassed to own Drag wheels.

I also hate those cheap wheels that have like 10 holes for mounting the lug nuts so that way they are universal. I used to be a mechanic at sears, and whenever those things come in, putting the rims back on the car is like trying to figure out a cross word puzzle, you keep turning until you find the right holes!!
