Hi all, up till this point in time I never had any understanding of offset...until I found 3 of my rims are shagged and have flat spots.. I'm just wondering if any of you guys have a similar setup to mine and might be able to point me in the right direction...

Basically I'm after some work meister s13p's, 18"x215/35 tyres.. It's for my 90model ef civic hatch. It's got crux racing suspension, type R integra control arms and is currently sitting about 140mm off the ground. It already has 18"x215/35's under it and they fit quite well. The guards have been rolled a bit more so there's plenty of clearance. Only prob is my exhaust is literally sitting on the control arm behind the shock..so will that effect anything?

I saw my local tyre shop and to be honest...was a complete waste of time. He didn't even come out the shop to look and just looked up the factory specs of 45 offset. I want a little bit of dish...but in saying that it IS a daily drive car. I would measure myself but I'm not 100% sure if ill do it right. Just asking some guidance if I could.
Thanks in advance
