Marc Newson Posted July 12, 2002 Share Posted July 12, 2002 When fitting 13" 'superlite' lookalikes, which ones fit over the AP 4 pot calipers? If I'm not mistaken: - UK Superlites need spacers - KN Minators (as supplied by Caterham) are machined specially for a direct fit - Panasports fit directly Has anyone tried the 'superlites' by Performance Industries out of Australia - do these fit? What are the offsets and other CRITICAL dimensions one needs to specify for 6" wheels (185x60 AO32Rs) at front and 7" wheels (205x60 AO32Rs) at rear when establishing whether 13" 'superlite' lookalikes will clear the AP calipers?

Graham Sewell Posted July 12, 2002 Share Posted July 12, 2002 If you look at the APRAcing web site, you'll see that they do templates for wheel clearances for their calipers. Unfortunately, they do not list the Seven but might be able to come up with something if you email them. Low tech luddite - xflow and proud!

F355GTS Posted July 12, 2002 Share Posted July 12, 2002 Marc K&N's do fit without spacers, £50 each plus VAT from George Polley (for a 6x13) however I have a pair of Superlites which also just fit without spacers although if the weights were fitted in line they would not clear sorry, don't know abouthte others Mark Link to comment Share on other sites More sharing options...
V7 SLR Posted July 12, 2002 Share Posted July 12, 2002 George Polley KN's just fit but you have to ensure that any wheel balance weights are not stuck on where they will directly pass the AP calipers because the clearance to the wheel is only about 3mm.

Harry Flatters Posted July 12, 2002 Share Posted July 12, 2002 The new UK Superlites definitely need spacers. New molds since start of this year. arrow.gifarrow.gifHarry Flattersarrow.gifarrow.gifthumbsup.gif AKA Steve Mell id=green> Link to comment Share on other sites More sharing options...
Tonycaterham Posted July 12, 2002 Share Posted July 12, 2002 Harry, Spacers...how thick for new 6x13 Superlites, so I can order them in advance,... please Tony Link to comment Share on other sites More sharing options...
Harry Flatters Posted July 12, 2002 Share Posted July 12, 2002 Tony, I never did use my Superlites, bought them then sold them on. I have split rim jobbies now. I do know "robmar" had them with spacers. Try here for his e-mail address etc. I reckoned that I would only need 3-4mm spacers. Good luck arrow.gifarrow.gifHarry Flattersarrow.gifarrow.gifthumbsup.gif AKA Steve Mell id=green> Link to comment Share on other sites More sharing options...
robmar Posted July 12, 2002 Share Posted July 12, 2002 the ones I have on my car are about 2.5mm without actually ever having measured them blush.gif and just appear to be flat washers! this gives enough clearance all round rob Link to comment Share on other sites More sharing options...
F355GTS Posted July 12, 2002 Share Posted July 12, 2002 V7 SLR My K&N's clear with the weights in line with the calipers, is it possible the spec of the wheels has been changed? although maybe the weights are only 2.5mm or so so there is just enough clearance, I bought the wheels about three months ago Mark Link to comment Share on other sites More sharing options...
V7 SLR Posted July 14, 2002 Share Posted July 14, 2002 Interesting. I bought mine at about the same time. I've got quite clear "reminders" on my calipers showing their coming together. I don't believe I am the only person to have found this problem but it is probably not anyway near as common as them fitting right first time as I've not heard of many complaints.

Jason Plato Posted July 14, 2002 Share Posted July 14, 2002 Are spacers safe ??? , as you would no longer have the central wheel mount being used on the hub face ???? I'd much prefer to have them designed to fit properly myself ? Dave Link to comment Share on other sites More sharing options...
Marc Newson Posted July 14, 2002 Author Share Posted July 14, 2002 Many thanks for all the responses. On the subject of offsets, seems that an ET19 offset (as per the original 7J x 16") will work for the 7" rears. What offset works best with the 6" front wheels (not forgeting the 4 pot caliper clearance)? Cheers Marc CUM B48 Link to comment Share on other sites More sharing options...
F355GTS Posted July 15, 2002 Share Posted July 15, 2002 Looking at my hubs I would have thought that if I tried to use spacers I would need longer studs Mark Link to comment Share on other sites More sharing options...
Marc Newson Posted July 22, 2002 Author Share Posted July 22, 2002 Just to close of this enquiry I am posting the following: Copy of the response from AP Racing regarding the 4 pot caliper size - "Generally we do have caliper profiles but the caliper we made for Caterham at the time (1996/7) was unique to them and as far as I can see there is nothing other than the machining drawings. The outer profile of the caliper will be 156mm from the axle center line and overall width of 124.60mm. All Cars used 13" wheels for both road and race our calipers were all designed for 13" wheels. I don't know if the Caterham wheel was specific to them or if it was a standard readily available wheel." Caterham confirm that the standard offset for their KN 6"x13" wheels is ET24, giving a back space of 125mm. Panasport wheels come in CLASSIC and ULTRA LIGHT - both fit over the 4 pot calipers.
