I'm thinking about putting hr31 struts into my 180b sss purely for the fact that you can bolt bigger brakes straight on. My question relates to how much offset I will loose. My mate has them in his 1600 and he is very limited to what offset he can run. I know that when it comes to offset 1600's and 180b's are very different that's why I'm asking the question. This topic has been covered many times before but not for 180b's. I have 15" x 8" with 0 offset wheels.

Is the same loss of offset on 1600 as on 180B. 180B just has a little more room inside the guards...
