Default 18" Oz wheels on a classic

Hello,

I know this question keeps coming up but I need a definative answer.

I've recently purchased a set of 18" Oz P1wrc allyoys to go on my Version 6 classic sti.
They are currently shod with 225/40/18 rubber and I know that there is sometimes an issue with this size tyre on a classic, but when I took the wheels to my local tyre dealer they wouldn't go on the rear as the actual alloy caught on the brake lines.

Does this mean I need a spacer and if so what size are people using for this?

I'm running 18" OZ P-WRC1's on my RB5 without any issues. They have 215/35/18 tyres on them just now, but I was running 225/35/18's before that.

225/40/18 is for a new age. Are you sure the alloys aren't off a newer car? They should have a stamp on the inside of the spokes with an ET53 offset if they are off a classic.

Just had a look and they've definately got ET53 stamped on the inside.

I'm surprised the wheel itself catches, usually, it'd be the tyre on the outside arch or arch protector.

Though what rear axle have you got? Unless it's a Type-R, it should be the same as the P1 - R160.

Did they try both sides or just the one? There should be a fitting guide around somewhere for when these were an option on the P1. (Though I haven't got it). That mentioned "manipulation" of various bolts, mounts and brackets "as required" to provide clearance. i.e. If it hits, you bend it out of the way.

I don't recall brake lines getting a mention though.

Ok, I offered one up today at the rear and it definately catches on the braided hoses that snake around the suspension, and even if I move these out of the way, the tyre and rim are literally millimetres away from the suspension strut itself.

So, think a spacer is the way to go, and have been offered two 6mm spacers from a friend which should do the trick.

My only concern is using a spacer obviously lessens the amount of bolt that the wheel nut can grip!!

Dave....true regarding the grip shortening on the bolt ........it should be "ok", but you can fit longer studs for peace of mind
