So tonight I tried putting my old tc1 rims on the FRS. Reason being they are my autocross wheels and tire. I could not get the rim to sit flat on the hub of the FRS.

It seems the Hub bore on the frs is larger then the bore on the tc1 wheels. I did try searching but does anyone know what the hub bore size is on the TC1 oem wheels? I'm going to have them machined out a little bit so I can get them to sit flat. Thanks.

54.1 for the tC1 I believe.

Thanks that's what I thought it was. It's one thing after another. Had to get flat seated lugs in m12x 1.25 that was a pain to find. Now I need the hubs machined out. Just a tad. Or for the wheel pros put there is there a easier way to make a conversion from. 56.1 hub to a 54.1 hub?

Welp i did mine today used old wherls from tc for now the hub centric rigs i had to shave them dow bo make it fit but it worked out

It will do for now till i decide on wheels

Only other thing I can think of is a bolt on spacer with the hub sizing to match appropriately, but I think machining the centers of the wheel might be a cheaper route.

Doper, most aftermarket wheels run a bigger center bore than 54.1, the factory optional wheels from TRD for the tC1 match the bore size. That's why all you had to do was shave the inner diameter of the hub centering ring to 56mm and able to throw the wheels on.

what did you use to shave em down?

doper

I used my old ones from tc for now they are 225/40R18. Potenza S-04

As far as shaving i used what u see in picture and saw blade but the other side of it and sand paper lol ghetto style but worked fantastic . It took a while on the first one but once u figure out what to do than its quite easy .
