I have uk brakes also I currently have 18's at 8.5j all round and have 10mm spacers just to push the wheel out to arch.....

Dnk Posted October 3, 2014 Share Posted October 3, 2014 (edited) They're the wrong PCD if they are 5 x 112 and 5 x 120 The mikv supra's PCD is 5 x 114.3 with a spigot diameter of 60.1 mm Edited October 3, 2014 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
Lee P Posted October 3, 2014 Share Posted October 3, 2014 As I said to you, 11j wheel with a 20 offset will need a lot of work to fit, probably an extended arch Jamie ran the 9.5j ET 20 on the back and needed the arches rolling Any wheel that fills the arch will need it rolling or cutting All the guys running wide wheels (11.5j ect) run an ET50 Quote Link to comment Share on other sites More sharing options...
sean2kuk Posted October 3, 2014 Author Share Posted October 3, 2014 Where could I buy a set in the 114 fitment I need? Nothing on ebay Quote Link to comment Share on other sites More sharing options...
sean2kuk Posted October 4, 2014 Author Share Posted October 4, 2014 Found a set on japshop......it says ET20 ...8.5j would I have any issues at that....? What does this ET mean? Quote Link to comment Share on other sites More sharing options...
Chris88 Posted October 4, 2014 Share Posted October 4, 2014 Found a set on japshop......it says ET20 ...8.5j would I have any issues at that....? What does this ET mean? ET is the offset of the rim. If you had an 8" rim with ET0 then the mounting face would be in the centre of the width and you would have 4" of rim inside the mounting and 4" of rim outside the mounting. ET20 means that the mounting face of the rim is 20mm outside the centre of the rim (20mm towards the outside). So if you have an 8" rim with ET20 you would have 121.6mm inside the mounting and 81.6mm outside the mounting. Once mounted on the car the ET20 rim sits further in and is less likely to need arch rolling etc. Clearly the wider the rims the larger the ET (offset) needed to avoid arch rolling. However there is a limit because as offset increases the inwards projection of the rim and tyre increases and there comes appoint where contact occurs with the strut.

Nic Posted October 4, 2014 Share Posted October 4, 2014 (edited) Stock Supra wheel/tyre sizes Front: wheels 17x8 +50, tyres 235/45ZR17 Rear: wheels 17x9.5 +50, tyres 255/40ZR17 http://www.nlmotoring.com/XXR-531-Wheels-s/1674.htm?searching=Y&sort=5&cat=1674&show=150&page=1&f-18%20inch%20wheels=614 Looking at the sizes available the following would probably be the best fitment if you don't want to roll the arches, the outer rim will be close to flush with the arches but as long as you don't go too wide with the tyres they should just fit. I have no idea if these will clear the larger 4pot/2pot Supra brake calipers though, this will depend on the design and size of the wheels, normally clearance problems are between the front face of the 4pot front calipers and the rear face of the front wheel spokes. Front: 18x8.5 +35 Rear: 18x9.5 +35 Edited October 4, 2014 by Nic (see edit history) Quote Link to comment Share on other sites More sharing options...
