Wheel clearance

Merv and Sharon · #1 (**permalink**) 06-08-2008, 11:17 PM

Thanks again guys. Yes the wheels are all flush on the hubs. There is some scope for minor skimming of the back of the wheel face but not much as there is only about 5-6mms between the caliper and the wheel now. I did measure the backspaces carefully and checked when they arrived. I checked with Warwick and mine is the R32 rear end (the spring passes thru the upper suspension arm). The ride height is 190 now and should be a bit lower when motor and g'box are in and that should also fold the wheels in a bit more.

Still a mystery! The brake rotors are new ones and I can't imagine that one could take (or want to!) much off them. The LHR side is better than the Right, which also puzzles me. I am starting to like the look though! Maybe I should bring one wheel down to check. I am planning to have the motor dropped in when it arrives in a few weeks and and could get this damn wheel aspect checked then. I was going to have it painted before rego but could delay that.

Hey this is sounding very familiar!
How did your rear end

end up Merv?

Merv, I spent an interesting morning at Matts' place, aka spookypt.

We put my Dragways on his Harrison and found to my surprise that they fit fine, just tucking inside the guards.

The only explanation that was confirmed by Scott at Venom is that I must have a R33 rear end. I had been told by the guy that i bought the car from that it is an R32 and he's ordered the wheels to suit Warricks spec.

So the lesson is don't assume that what one's told is correct.

The R33 is wider than the R32 (as I think you already know)

Anyway, Matts' RF Racing 17" wheels with +50mm offset (plus a 25mm spacer) are a perfect fit. Not Hallibrands but apart from the wrong colour look pretty smick. The next question is, will Mr Cross accept spacers? If not I'll leave them off for rego.

I'll persevere as you did with your wheel combo, I still can't fathom how you tucked them under the guard, i'll revisit this after paint. She's off to Des the painter in a few weeks......should be home before Chrissy for trimming up.

The R32 camber arm has a 'ring' for the shock to pass through (ala the links Sambo supplied in your other post), while the R33 has a camber arm that runs around the front (or back - I'm not sure) of the shock. Given Merv's experience and yours, I guess the 32 and 33 rears are different widths.

Oooohhhhh no Geof, there goes my theory. The shocky and spring pass through the ring.
Are you sure there's not a couple of arm configurations for a R33?

Greg,
What chassis number have you got? Should be able to work out if it R32 or R33 from when it was made.

Hi guys, I'm putting a R33 rear end in my Harrison & Warwick tells me that there is 10mm difference between an R32 & R33, with the '33 being the wider of the 2. Therefore I'm going to need adjustable camber arms to make it work. That was never going to be an issue for me as I have already bought all adjustable arms to I can adjust Camber,toe & caster as well.
Hope it helps

It's #38, about 2004 vintage, having sat in a workshop for a few years before i bought it in 2008.

Yeah, i recon a bit more than 10mm, if indeed mine is an R33. Anyway, I think I'll grab a set of adjustable arms as you have done. Hopefully I'll be able to squeeze the Dragways inside the guard with these. Be careful with offset measurements if you havent bought your wheels yet. With R32, Warwicks' 130mm recommendation is about right but if R33 you need to decrease this to around 110mm. Also remember that if using Dragways Hallibrand lookalikes that you may have issues with the 'spokes' hitting the brake caliper.

Greg, I'll go find some i/v's for what I bought. I'm very happy with the quality of what I bought, its all well made & well finished, so I'll let you know
