I need to find out will the Alliance 8pistons Front and 6 pistons Rear fit on 20" Work T1S with +15 offsets all around (Front 9.5 R and rear 10.5 O)?

The alliance calipers are 139.7mm (5.5") wide and I believe they are smaller then the rotora 8 pt calipers if that makes a difference.

Also, I know the alliance BBK will fit these rims and offsets for sure:
1. GT7 20X9.5 +23 / 20X10.5 +26
2. CE28N 19X 9.5 / 10.5 +22 all around
3. GT30 20X9.5 +23 / 20X10.5 +24

 

buy them and try it. just in case it doesnt buy some spacers quick fix

 

How close to some of those others are they? Based on the offset and wheel face style it's going to be very close and I would bet they won't.

 

impossible to know without knowing what face is being used

 

Isn't the R and O disk the face?

 

yep, totally didn't read that part

 

hehe, I'm not a wheel ***** so I don't know the different faces from work and the others like that.

Help the brotha out!

 

well r disk is for bbk fitment, so yes it should fit, the rear im not sure

 

aren't u running the O dish in the rear also with 4pot?

 

I found a thread where jjyellow was running 20X9.5 +7 R and 10.5 +0 O with his rotora but I'm not sure if those are 8pot/6pot. Can anyone tell or know? If rotoras fit at such a low offset shouldn't I be good at +15 all around?

 

They should fit easy, if I remeber correctly alliance calipers are not as wide as rotora.

 

the wheel ***** god has spoken!

 

you can also try an offset calculator to get an idea of the inner clearance from your current position, that might help

 

^That wont matter for caliper clearance!

 

edit: nvm do what shane says
