Jon Ward Posted November 9, 2010 Share Posted November 9, 2010 Hi All, A technical question, but I thought I’d try here first... I need to sort out a set of wheels for Class 2 next year. I’m going to try the Team Dynamics Pro Race 1.2 (7.0 x 15) with 195/45-R15 Scudo Stunners. Do I need to specify an offset, and if so how do I calculate it? I’ve done a search, but can’t find anything here or in tech talk The alternative is to get my shiny anthracites and nearly new Stunners back – you know who you are Maybe you could drop them off this evening 😬 Thanks in advance Jon Link to comment Share on other sites More sharing options...

Area Representative Richard Price Posted November 9, 2010 Area Representative Share Posted November 9, 2010 Jon, Caterham ten spokes are 6.5" ET13, but are quite outset. If you were specifying 7" wheels, then you could still cope with ET13, but no more. ie ET10 or ET8 would ne better. If the ET value was too great, say ET 18, then you could use a 5 or 6mm spacer, as long as you have long enough wheel studs. I've got a bent wheel you could borrow for comparison if you like?

Jon Ward Posted November 9, 2010 Author Share Posted November 9, 2010 Richard Their website lists 7.0 x 15 e15 / 23 / 25 / 30 / 35 / 40 / 45 So if I understand you correctly, I need e15 and some 5mm ish spacers (?) Link to comment Share on other sites More sharing options...
Mr Locust Posted November 9, 2010 Share Posted November 9, 2010 Jon, Full tech here You could always source a reasonably priced set of 6.5j x 15" ET13 Prisoner rims locally Ian Green and Silver Roadsport 😬 My Flickr Photos Blatchatters Flickr Pool Link to comment Share on other sites More sharing options...
Area Representative Richard Price Posted November 9, 2010 Area Representative Share Posted November 9, 2010 Jon, ET15's will be fine on the rear, but there is a good chance you'll need a few mm of spacers on the front. I'd get the tyres on the rims before deciding on the spacers that you need. If you do need spacers, then you may also need longer studs. (all later hubs are supplied with longer studs) Link to comment Share on other sites More sharing options...
Area Representative Nick Chan Posted November 9, 2010 Area Representative Share Posted November 9, 2010 I've got a bent wheel you could borrow for comparison if you like? I thought you had a full set available or have you disposed of the real bad ones apres-Landow 😬 The alternative is to get my shiny anthracites and nearly new Stunners back – you know who you are Those will be the lightened version then - well, they haven't got much tread left Back in a BEC! - but done alright in Class 1...

Jon Ward Posted November 10, 2010 Author Share Posted November 10, 2010 Thanks chaps, After talking to Richard earlier, I'm going to have a rethink before spending a load of money on something I might not need... At least now I understand the meaning of offset Br, Jon Link to comment Share on other sites More sharing options...
