The "Will These Wheels Fit My FD" Question Eliminator 3000
 

https://img129.imageshack.us/img129/...00smallke0.jpg

An XLS File Based on tried and tested setups. The code is based off of the tried and tested 18x10+50 CCW setup with 2.5" coils and Rotary Extreme Trailing arms, and the proven 18x10+42 on all corners with stock springs and trailing arms. The code will adjust according to your wheel widths, offsets trailing arms and coil setup to provide you with setup verification, and or an explanation of why it won't fit referenced to a explanatory diagram. The Eliminator will also automatically convert your wheel into metric and provide you with "true" front/back spacing. Please keep in mind that these numbers are based on extremes so don't try to push your offsets too the limit. To generate more accurate setup verification, I recommend entering your tire width into the Eliminator in place of rim width. I haver included a conversion tool on the right hand side that will convert your metric tire widths into a standard format that is compatible with the Eliminator. Just plug the converted/adjusted nominal tire width measurements into rim width fields and you'll be ready to verify.

We're all tired of the same questions day-after-day. It doesn't get any easier than this. Mods, lease make this a sticky.

Enjoy ;o)

Please feel free to PM me with recommendations for front wheel limitations with stock springs. I can easily update the Eliminator settings if we find something that works better for us.

Haha! Nice work. :)

Nice spreadsheet, Wanklin. Of course, we'll still see a bunch of "will these fit?" threads, since not everybody wants 18s. Also, you might wish to redo your example picture, which makes backspacing appear unrelated to offset.

It'll do the job for most of the basic questions out there. The difference between 18" spacing and 17" spacing is very minimal since the trailing arm angles are pretty close to perpendicular. Using simple trig we could calculate exactly how much of a difference there is, but I'll save that for another time.

Thanks for the suggestion, it always helps to have a second eye. I'll change the pic when get time.

Eventually the spreadsheet will be able calculate diameter variances and allow you to select flare options etc., but for now I think it will answer 95% of the "will it fit" threads.

thanks,

The server sucks.

Once I get a chance to download it (probably next week) I'll rehost it.

Nevermind, the server's script wouldn't work with firefox.

I can rehost it for you if you want though.

Will you be willing to upload occassional updates? ;o)

i wish i had excel

Absolutely. You'd just have to send me a PM or something whenever it's updated.

Sounds like a plan ;o) What email address can I send the file to?

Screw Excel...use OpenOffice. It's spreadsheet program will read and write Excel format, and it's free.

Send it to thephil@kitsunedev.com.

Also, I don't come into this subforum often, so PM me if you have any questions or anything :D

Please check your email ;o)

Done :D

Not a problem. When I get around to it, I'll stick a hit counter on there too. But as for now, I'm too lazy :D

You're a good man.

nice, it was very helpful.

glad to hear it.

Not exactly accurate. My father and I both run 18x10, 45mm offset, 285 series tires on the back of our stock suspensioned FD's. They fit perfect and according to that excel sheet they don't. But it is a good tool to get you down to the right area.

Did you enter the wheel width or tire width? If you enter the tire width the results will be slightly on the conservative side. I do plan to tweak that in the future, but as you say, it's good enough to get you there for now.

I entered both just to see what it would say. It said too much backspacing on both. But yeah, better to be a little conservative than not.

[q]Using simple trig we could calculate...[/q]

That is great! LoL.

Tim what setup are you running up front?

Are you running stock trailing arms? If so, I will use your feedback to retweak my tolerances for stock springs/ trailing arms.

thanks
Rob

Also if you guys with aftermarket flares start providing me with some fitment info I can look into adding flare features into the "Eliminator."
