can any one tell me if the pommy x pack mk2's had a wider track width i;m trying to get an arched car rego'ed any that might be the thing that saves me getting new wheels for rego thanks the widest track i can find is a unarched rs1800 in uk front 1310mm rear 1320mm but i really need series x track

I don't think the track changed but they typically used 7.5" wheels, which were wider on the outside. Therefore, the overall track width from edge to edge did change but not the hub to hub width. That make sense?

thanks smicka but i found out that the engineer is just going to measure from tyre center to tyre center would you know that measurement

no. Jump onto a Uk site as they will have more Xpacks than we have

when you upgrade to bigger width wheels and the track needs to be checked for modification paperwork. is it the centre of the wheel/tyre the measurement they take, also what's the maximum increase in width of the track you can have? my car has 8 x 16 inch ET+25mm wheels as standard and i want to go to 9 x 18 ET+20mm. as i work it out even though i am going 1 inch wider wheel i am only really going +5mm increase in track each side, 10mm in total. is that correct?

Plug your info into this page and it'll give you the answers.
