davebo Posted November 3, 2007 Posted November 3, 2007 Not sure what wheels to get for my Seiw build (detachable wheel arches). Halfords have some Pro race 1.2s that I like. 15". Quite a few people seem to have these having looked on this website. What sort of offset do I need ? ET38 is what halfords seem to do, but the Rimstock website suggests they do them in all sorts of ET. I imagine I'll probably need spacers too. Any idea where I can get these from ? are there any issues with using spacers - I guess there must be a maximum from a safety point of view. Thanks Quote
davew Posted November 3, 2007 Posted November 3, 2007 afaik et38 should be fine. I have superleggeras 7x15 in et37 and they fill the arches out well. Quote
Underground Ernie Posted November 4, 2007 Posted November 4, 2007 I have Pro race 1.2's on my SEIW with detatchable rear arches with a offset of et23. They fill the rear arches perfectly but I had to fettle (bend) the cycle wings. I think with et38 you might need spacers to fill the arches out nicely. I didn't want to use spacers. This is my car fitted with et23 1,2's. (sorry it's not the best picture, but you can just about see how close they are to the arches) et38 wheels would sit 15mm further inside the rear arches. Hope this helps. Mitch Quote

Thanks Rimstock / Team Dynamics will make the wheels in any offset you want, mine are et 20. Give them a call 0121 525 6500. Why don,t you first see if there are any members close to where you live, who can lend you a wheel and tyre to try, any offset would do, then measure to the outer edge of the wheel arch to determine the perfect fit. Better result than fitting spacers. Quote
Martin Keene Posted November 4, 2007 Posted November 4, 2007 Halfords will be buying them by the container load at one offset for a stupidly cheap price. Great if that offset suits you, not so great if it doesn't. As Mid Life said, Team Dynamics will custom make a set to whatever offset you want, whilst there will be a cost implication to this, I don't believe it will be a lot as it is a very simple change to the CNC progam to produce what you want. Great wheels as well, very light for a 15" wheel. Quote
scott beeland Posted November 4, 2007 Posted November 4, 2007 Machining custom offsets depends very greatly on the amount of material available in the mounting face of the wheel. Manufacturrs/ wheel designs vary greatly and some designs simply don't allow machining Quote
Buzz Billsberry Posted November 4, 2007 Posted November 4, 2007 On the other hand scott don't 4 get most cast wheels are built for 1.5 tonne tin tops you'll have enohugh to play with is some cases to remove a good bit of materials as I did with the compomotives. Buzz Quote

Manufacturrs/ wheel designs vary greatly and some designs simply don't allow machining Not sure if I'm right about this Scott, but bare with me. If you want to decrease an offset, isn't it a case of leaving more material on the inner face of the wheel, ie machine less. If you were to start off with an ET20 then machined off 18mm would you not end up with an ET38 and a further 18mm would then give you an ET56, if there was that much left on the billet. Quote
scott beeland Posted November 4, 2007 Posted November 4, 2007 Yep. I was mearly pointing out that some wheel types/ designs won't allow for further machining than they already have at a specific offset. TD wheels usually have quite a lot of mounting face material though Quote

davebo Posted November 4, 2007 Author Posted November 4, 2007 Thanks for the help. So if I do buy wheels with Et 38 mm, I'll likely need spacers at the rear to get the wheels to fill out the arches. I take that for Ernie's Et 23 wheels, he had to bend cycle wings to make up for the smaller offset. Which I guess means Et 38 might be ok for the front. And whatever happens at the front, I can bend cycle wings to accomodate? Quote
melt Posted November 5, 2007 Posted November 5, 2007 davebo, I have ET38's on a 2002 SEIW, fine on the fronts, have 10mm spaces on the bolt on rear arches. HTH Mel Quote
Big R Posted November 5, 2007 Posted November 5, 2007 Halfords are supplied wheels by http://www.mswuk.com/ When I couldn’t get the offset I needed from Halfords, I went straight to Motorsport wheels and they offered me an even better deal …… They understood what I was looking for and offered great support, which is more than can be said for Halfords.

chappers Posted November 5, 2007 Posted November 5, 2007 My Team dynamics Pro race 2 are 7x15 et +35 all round on a 2001 SEiW. I went for et+35 because I didn't want any hassle bending my front cycle wing as I had +35 on there before and my front wings are already very tight (like 2 mm from the stays to tyres). I run a 12mm spacer on the rear to make them et+23 (with 63mm wheel studs). I could have bought et+23 for the rears but I went for the same so I could rotate tyres if need be. My brothers SEiW he has just ordered apparently comes with et+23 pro race 1.2s all round with front cycle wings/brackets to suit et+23, and also no need for a spacer on the back. Pro race 2's are apparently being discontinued soon which is why my brother swiched to 1.2's instead or pro race 2's. Not sure but you might be able to specify black or silver for the centre cap - if you're bothered. Not a good pic, but this is et+35 without the 12 spacer. Looks way better when it is et+23. Quote
Steve Williams Posted November 13, 2007 Posted November 13, 2007 My SEiW has 15x6.5 wheels with ET33 on the front, same on the rear with 20mm spacer, which makes an effective offset of ET13. The original 15x7 wheels had ET38 on the front and ET16 on the rear. I wouldn't want to try any less offset on the rear, it seems about as much as the wheelarch will take. Quote
