I'm only running a 245 series tire up front. My father is running a 255. We both have stock trailing arms, 18x8.5" +45 offset.

I have emailed in the revised file, but it will not be on the server until xthephilx has a chance to post it. Rob |

Can anyone give me some advise?
I recently bought a set on new alloys ADR size 18inch 8.5J with offsets 35 & rears 9.5J with offsets 35 & was going to fit 225/40/18 tyres on front & 255/35/18 tyres on rear. Can anyone tell me if these offset of 35 will fit my car, Mazda RX7 1993 model twin turbo. The wheels i have on at present are 17inch 8.5JX with Offset 45 on front & 17inch 9.5JX offset 45 on rear. I'm a little confused as some people say they fit & some say the rears are too wide. Please help before these arrive. Dave |
No, they won't fit well. Offset is too low. Rolled front fenders will be a requirement. Also, proper fitment to me means more than just fitting inside the fenderwell, it also means maintaining the proper scrub radius/suspension geometry. +35 is too low of an offset for that.
The wheels you have now are damn near perfect fitment. I would stay with them. 17" tires are cheaper too. But if you want to run the ADRs you just bought, I would go with 245/35 fronts, 265/35 rears. |

question! the front spacing and back spacing... do they always remain constant? i read the example stating only fill in the yellow areas but im just making sure. i was told that the wheels i am looking at 18x9 +35 offset with 255 all around. i was told the front end might rub a little. does the guide a full proof way to check for possible rubbing? can anyone clarify this for me?

^ yeah yeah yeah i know i acknowledged that the sheet states the yellow boxes to be filled in. yet a respected member here told me that the fronts would rub in the front. yet the chart states the wheels will fit. so im just wondering what the chart exactly means by "fit".

Sorry, I misunderstood your question. There is no guarantee that the fronts won't rub, there are just too many factors that come into play once you allow the wheels to pivot. For example the 18x10 +50 CCW track package rubbed slightly on the front of Nick Y's car, while others with the identicle wheel/tire combination have not experienced rubbing. It's really a matter or ride height, spring rates, suspension variances, the way the the fenders are bolted on etc.
The spreadsheet will get the wheels to fit inside the wheel wells, but the rest is up to the individual owner. I hope that answer was sufficient. |
well according to the spreadsheet the wheels will fit. think i should try my luck and stretch to 265 all around :) ? i wish the spreadsheet would let you put in tire size (hint hint). should i just get my fenders rolled or maybe get some aftermarkets with a very slight flare? the point is i want wheels i can rotate around.

ok so lets imagine i can either put 265's all around or 255's all around. what do you think the fitment would be with the BFGoodrich KDW2's? any idea what fender rolling costs? i might as well get it done...

OK great tool and all but I don't have specific wheels in mind, I want the widest front and rear tires I can get with a stock suspension on a 93 base model. I've seen 285 all around but I dont want rub and I dont want to roll my fenders. oh and I don't have $5000 to spend on wheels I want some off the shelf wheels with lots of rubber can anyone help, thanks?

This "Question Eliminator" link doesn't work
None of the fitment links on this forum seem to be working.
|
Yeah it would be nice if this was available again.
|
Can someone tell me if I can fit these wheels on my 1985 gsl se. The wheels I want to put on are 15x7 et +9.. I plugged it into the configuration table but I don't understand it. Thank you very much in advance.
