Flush Fit Wheel Fitment, Offsets for Flush Fitment which is Proper Fitment Options

[stl95celica]

okay so im ordering Diamond racing wheeels and i dont know what backspace to get. This chart https://www.rsracing.com/images/tech-wheeloffset.gif says i should get % inches for front and back? im getting 15x8 and i want it to sit flush

[HectortheRican]

That chart makes no sense to me. What's backspace?

[stl95celica]

im getting these Click. and they do offset by backspace i gues and the chart is like a conversion sheet i think. im getting 15x8 and its only a 1-5 inch backspace and im pretty confused

[HectortheRican]

I'm thinking of the backspace as a spacer and if it is like a spacer, it doesn't make sense, the larger a spacer, the more negative the offset, this seems to be the opposite.

I'm guessing you'll be using those wheels for track/quarter mile use?? And please give us more pics of your SSR Type C setup in the official post a pic of your 6gc thread!!

SSR Type C's are awesome rims

[stl95celica]

The SSR's looked great on, But i smashed one last winter so there not on anymore. ill try and see if i have any good pictures of them on. the fitment sucked though


Does anybody have any idea how backspace works?

Oh those diamond racing rims are awesome. Ive seen some on hondas and they look great. Definately get them. And better off giving them a call and ask them about the backspace and how they measure it.

i almost bought some dimond racing steelies but then i found a great deal on some 7th gen with mint toyo proxres4 so i got them instead.

btw what would i need to make the 7th gens flush? offset is 39

[Promasta]

35 mm spacer.

problem with the 7th gens is they are only 6.5" wide, thats narrower than stock lol

[Driver]

35 mm spacer.

problem with the 7th gens is they are only 6.5" wide, thats narrower than stock lol

Is 35mm for front and rear?

[stl95celica]

So Ted did figure out what backspace was?

[Ted95]

35mm huh, ya im not going to put a 35mm spacer on my car lol, thats more then an inch right?

im in the process of a 3rd gen swap, i feel like with the power the 3rd gen will put down i will end up breakin something lol

and no i dont kno what back spacing is. i didnt look into it to b honest but if i had to make and educated guess i would say the space between the inner part of the tire/rim and the strut? lol idk man dk much about offsets thats y i asked my own question.

[stl95celica]

AHHHH i finally figured it out. expect some deep dish steelies onn my car soon

[Ted95]

[Promasta]

35 mm spacer.

problem with the 7th gens is they are only 6.5" wide, thats narrower than stock lol

Is 35mm for front and rear?

30-35 mm spacer for front.
40-45 mm spacer for rear.

don't do it.
if you're going to go flush(ish) don't do it with wheels that are narrower than stock.

ya after seeing how big of a spacer i would need im not going to lol its just not worth it

ok so i'm having some trouble getting this, guess i'm a little slow... I want to buy a set of wheels that are 17x8.5 w/48 offset. SO what sort of spacers do i need front & back fellas?
thanks.

You'll need 21mm spacers for front and 38mm for rear. Remember, that's for hellaflush. If you want just a nice, functional flush, I'd say 15mm front and 30mm rear would do nicely.
