Wheel Fitment Database/Summary/Grid

We have the wheel fitment thread sticky, but there's no easy way to find all the options out there (and results) without reading through it (painful).

Here is a Google Doc that Flyzipper shared with me. I've modified it a little bit so that we can try both M and non-M fitments.

Please feel free to add your information to the list. Here is the link.

Would be very useful I find myself in this boat now as I try to dig around for specs to see if Breyton makes a Race GTS in an 18/19" that fit the Z4

good idea

we can also auto calculate the effective offset when someone is using a spacer

There already is a google doc someone put together but I can't find it. Perhaps you can use it/tweak it without starting from scratch.

Thanks, I'll search. If it's public (or if I can find the source thread here) that would save work!

It must be somewhere in the Definitive Wheels Spec thread. It's pretty detailed.

Spreadsheet via Google Docs, that way you can add filters for m vs non-m, diameter, width, etc

OR

just create a spreadsheet with a calculator built-in. It won't be 100% absolutely correct (tire width will vary by make) but at least for stock suspension it should be close enough. If someone gives me baseline clearances on strut & fender sides, I can create a spreadsheet that will do the rest.

Spreadsheet already exists as Aestheticstorm noted.

I cannot be edited however, and we'd need to add a few more data elements. the good thing is that it's a really great start, and has data already.

I've PM'd the spreadsheet owner regarding using their spreadsheet, or using their data for a new one. I've asked that it be opened to editing (like the battery summary spreadsheet), since allowing folks to add their own data (if they have the right link) is just easier than trying to maintain it.

Once I hear back, and we have a plan, we'll move to sticky the thread with the existing spreadsheet or this thread, and then open it for data entry/viewing.

^Yep

Got access from Flyzipper, and I'll add a few fields and get it stickied after Christmas.

My z is lowered by h&r spring, does this spec apply to it as well? I phoned BC racing in Taiwan and ready to get HB 09s. They recommend about the same spec F +35 8.5 j. R +45 9.5j. Any suggestion ? Thanks!

outer clearance extending 24mm means its like putting on a 24mm spacer

the 14mm less inner clearance means it will be 14mm's closer to the shock
