What model is your RX8? Why would you want to run staggered RX7 wheels anyway?

lookitsjeremy

Because I have them and nobody wants to buy them. So instead of the letting the tires dryrot I figured I'd use them.

Not really a will it fit question, but if I want to use my CX-7 wheels to commute to track days that are far away, would that be a generally good or bad idea?

Specs:
18x7.5 +52 (50 or 52, not entirely sure)
225/35/18

I also have a set of Mazda 3 wheels, 17x6.5 +52, but clearance might start getting sketchy...

20x8.5, and 20x10 all four with +25 offset, will it fit? i know i will have to run 245 in the back and 225 in the front to get a decent stretch and got to roll the fenders but i just wanna get another opinion on what i should do and if itll fit good

oh lawd...

your car is gonna look like a japanese chevy.

fyi people are running 11's up front in the +20 offset. You're talking about doing +25 with 8.5 and stretching tires...

math...it helps

No, the wheels are on my Mazda 3 now. Hence the spare Mazda 3 wheels

You can but speedo will be way off and gas mileage will be even worse due to shortened sidewall.

AZ R3

should I go with 225/45?

Here's what I get for going from OEM 225.45.19 to 225.35.18, left column old right new:

Diameter 685.1mm 614.7mm
Circumference 2152.3mm 1931.1mm

Reading at 60mph 60mph 66.87mph
Ride height gain 0mm -35.2mm
Arch gap loss 0mm -35.2mm


And this if I put 45s on (35 was just for looks on the 3)

Yes I can do math. Pretty sure it is 225/40/19 stock for an r3

AZ R3

Thats what I meant

Benji_rx8

Ok so I just got some 18x8 et30 on 225/40/18 (front)
And 18x9.5 et 26 on 265/35/18 (rears) dropped on h&r springs (1.5" drop) will it fit!?!

Thanks guys?

J8635621

Sounds like you have them. Put them on.

AZ R3

Step 1: Buy a helmet

Step 2: Put on the helmet.

Benji_rx8

I know they will fit on stock suspension but I was just hoping someone might have a clue wether they will be ok with the drop before I fit the lowering springs as I've heard h&r tend to drop quite low so just wondered if it's worth a try or Deffinatley won't fit? Cheers again guys!

Your definition of fit must be different than mine. That **** would be way out there

cyler

Looking at 18 X 8.5 35 offset running 255/35. From what I have read it seems like it should be fine but I just wanted to make certain before ponying up. This is good right?

run 245/40. it's a better fit and closer to stock rolling diameter

AZ R3

Noob time


When you say rolling diameter, do you mean circumference?

Or do you mean diameter...in which case why say "rolling"?

fuztupnz

iTrader: (4)

no i meant diameter. I could have said outside diameter instead if it clears it up.

I found a cheap set of rims for an '06 Mazda Miata.
They are 17x7, 5x114.3 bolt pattern, 55mm offset

Will they fit on my '06 Rx8 with a dropped Tokico D-Spec Suspension?
I have 17" wheels with tire size: 225/45 on the front & 215/55 on the back

Thanks!!!

The only issues you'll have are making them look good or perform better than stock...

I don't remember the specs for brake clearance. Test fit in front before buying
