Area Representative IanW Posted March 16, 2010 Area Representative Share Posted March 16, 2010 Hi, Time for a question about which wheels to use for my first track day. I don't really want to use my CR500s on the track, so I need some replacement wheels (and tyres). I am trying to source some replacements for the 15" anthracites from Caterham. Are these from Halfords suitable? If not, where else should I be looking? Regards, Ian. Link to comment Share on other sites More sharing options...
jonboylaw Posted March 16, 2010 Share Posted March 16, 2010 Not my cuppa tea.. Try contacting Polley motorsport for a set of minilights and decent tyres. The website is here Also search the for sale sections and also cosider going to 13inch wheels as there are lots more tyre choices available.

Area Representative Richard Price Posted March 16, 2010 Area Representative Share Posted March 16, 2010 Ian, if you're looking for another set of wheels, then you need to specify the stud PCD (which should be 108mm for a dedion car), and the offset. Caterham 6.5"x15" ten spokes are, I think ET13. Most aftermarket wheels for modern FWD cars tend to be more inset (ie, have an ET value greater that ET13), and may need spacers (and maybe longer studs) to give adequate clearance. Why do you want a set of 15" wheels? There is not much tyre choice in 15" suitable for track days other than CR500's. If you're going to buy another set of wheels for track days, you'd be better off buying a set of 13" wheels, and running something like Yoko A048R's, or Toyo R888's in 185/60-13 all around. These are great track tyres, and about the same overall diameter as your 195/45-15 CR500's. Link to comment Share on other sites More sharing options...
Rattie Posted March 16, 2010 Share Posted March 16, 2010 Bear in mind that most cheapo boy racer alloys are made down to a price. They're heavy and usually pretty soft, designed to be mounted on cars where it won't make much difference. It pays to seek out lightweight wheels.

7Nut Posted March 16, 2010 Share Posted March 16, 2010 A few choices here If you do go down the Halfords route, don't forget the club discount. Cheers, Stew My 7 here Link to comment Share on other sites More sharing options...
Area Representative IanW Posted March 16, 2010 Author Area Representative Share Posted March 16, 2010 Thanks for the replies. Jon: I'll try Polleysport to see what they have available. Richard: Bl**dy Acronyms! Bane of my life 😔. PCD I guess is the diameter between the stud holes. As for ET13 I have no idea . Next question: Assuming I go for 13" wheels, what widths should I be looking for? I see references to 6, 6.5 and 8 inches but I don't know what I need or what will fit the car? I'm constantly plagued by too much choice when trying to make buying decisions . Regards, Ian. Link to comment Share on other sites More sharing options...
Area Representative bluenose Posted March 16, 2010 Area Representative Share Posted March 16, 2010 Ian For trackdays I would recommend you use 13" wheels. Your best bet is to buy a set of used wheels that come up for sale on here, the Westfield forum, here or Pistonheads here or Ebay here Your car will need wheels with the 4 108mm pitch circle diameter stud spacing that has been mentioned and must have offsets of +23mm for 6" wide wheels and +18mm for 7" wheels although and this is usually marked on the rim with ET and then the number. Other offsets will probably fit though. If your car is less than 140ish BHP then 6" wheels all round will probably work well, if your have more power then 7" or 8" will be OK but it really depends on personal choice, and larger Carlos Fandango wheels do look good Nick Lava Orange Caterham Blackbird Link to comment Share on other sites More sharing options...
Roger Ford Posted March 16, 2010 Share Posted March 16, 2010 Don't forget that wider rears (a) cost more to put rubber onto and (b) prevent you from swapping front to rear as the rears wear down. Link to comment Share on other sites More sharing options...
Area Representative bluenose Posted March 16, 2010 Area Representative Share Posted March 16, 2010 Oh, and beware of ACB10 tyres and some slick tyres as they are crossplys and not really suitable for quick swops from road to track as the work better with different camber angles.

Area Representative IanW Posted March 16, 2010 Author Area Representative Share Posted March 16, 2010 So for a Roadsport 175 SV, I'll be looking for 7 or 8 inch wheels. With regards the ET. How do I measure the minimum and maximum values I'm allowed? Does the size of the tyre have much influence on the results? Regards, Ian. Link to comment Share on other sites More sharing options...
simonpa Posted March 16, 2010 Share Posted March 16, 2010 Hi Ian, where in Hampshire are you? I'm in Fleet and have several (!) sets of wheels in different widths if you want to check some of the options... BTW, the offset for 6" & 8" wheels are both 24.

Iain A Posted March 17, 2010 Share Posted March 17, 2010 Hi Just to say that the offset is Very important. I have 3 sets of wheels with offsets of 13mm, 18mm and 24mm - all are very different and have a great effect on steering weight. I like the 24mm ones best - that is the standard offset on Caterham 6" x 13" alloys as far as i am aware. Don't worry about going too wide with things. Narrower is more progressive on the limit (so more fun near the limit). I have 220bhp in a fairly extreme car and am happy with 7" rims with slicks in the dry and 6" rims with Yoko A021 in the wet. Same width front and rear - the car balances better. If you are new to trackdays - go for the cheap option of some used Caterham 6 x 13 alloys and put your tyres of choice on them for a play (used slicks are the bargain fun option). If you want to go wider later.. you can still use the 6 x 13 s in the wet with a set of A021 and use the new wider rims with the slicks. Works for me. Have fun One of the Duratectives Link to comment Share on other sites More sharing options...
Ian R Posted March 18, 2010 Share Posted March 18, 2010 Ian Go check out Piston heads classified as there a few sets of 13" rims in there worth having. http://www.pistonheads.com/sales/list.asp?g=3&s=395&filter=&o=&pc=&min=&max=&txt=&px=&p=3&pagesize=15&xsl=list&y1=&y2=&d=0&dist=&nodays=0 Ian (C4T VX) (If you want to go faster, you will have to add lightness!)

Willie. Posted March 18, 2010 Share Posted March 18, 2010 Alternatively, if you're on a really tight budget...Peugeot 305 rims fit and work. I put a pair of old T1Rs on a set for a trackday, intending to use them for hooning. Ended up loving the way the R888s on my "good" rims felt, so scrubbed them off instead. I have a set of steel 8spoke wellers which I've just had blasted/coated and am for using for a trackday set. Willie Link to comment Share on other sites More sharing options...
Tony Whitley Posted March 19, 2010 Share Posted March 19, 2010 Or you could just borrow some. You'd have to promise to treat them properly though Link to comment Share on other sites More sharing options...
akakubi Posted March 19, 2010 Share Posted March 19, 2010 My vote goes to Compotitive CXR. You can get them in many shades of grey as I recall. I went with 13" and Yokos A048 combination (185/F and 205/R). The guys over there will do any offset you specify. And the quality is great.

Tangerine Dream Posted May 29, 2010 Share Posted May 29, 2010 Somehow missed this thread when it was current. I am looking for track wheels also. I am about to buy some new wheels having failed to find what I want secondhand and will probably splurge on the 13X6" black minilites with polished rim that CC do. Tyres will be AO48/888. Front tyre will be 185/60. Rear can be the same or 205/60 .. neither will upset the corner weighting. The car is a standard R400 SV (210bhp). Is 185 on the rear too little or should I stick with a 205? ================================== R400SV in orange - so far unmodified! Link to comment Share on other sites More sharing options...
simonpa Posted May 29, 2010 Share Posted May 29, 2010 Crikey - quite expenssive for a track solution, especially as teh polished rim will start lifting in a couple of years. IMHO, the 8-inch rears give better track handling - even on a 120bhp car. If you are interested, I have 2 sets of the CC 8-spokes in 6/8-inch in black. They will look fantastic on an orange car. I am currently 7-less, so need to clear down some of my 'spares'... Cheers - Simon Link to comment Share on other sites More sharing options...
Roger Ford Posted May 29, 2010 Share Posted May 29, 2010 Those minilites are almost exactly the same price as the 8-spokes, which are 3/4 of a kilo lighter (each). I'd talk to Simon... Note there's an advantage in running 6 inch / 185 all round as you can swap front and rear as they wear. Link to comment Share on other sites More sharing options...
