M12x1.5 I would be looking for steel ones not alloy like the d1's Be careful on ebay there are a lot of fakes d1, project kics and rays are all faked out there.
Has been for sale for some time over on tocirl did have a cage fitted and some other parts would have thought it would have sold before now if it was as tidy as it looks
Fake for that money, would be at least double the price if they were real. Go price them up on RHD Japan for an idea of what a real one costs. There is a lot of fake and copied suff on ebay these days.
Steve measure across the bolt holes to get the PCD of it then check it against the ones for sale there are 2-3 differnt pcd's used by steering wheel companys
Yes they are the same as Alan's wheels This starlet for sale has them fitted: http://www.ebay.co.uk/itm/Toyota-starlet-ep91-ep-91-glanza-v-1-3-turbo-white-import-not-ep82-/230838617283?forcev4exp=true
Few ideas: Have you got the correct HKS FCD for a starlet? Does it hit fuel cut with the boost turned up without the FCD fitted? Just wondering if you have a mapped ecu in there thats not marked up and the fcd is upsetting it. I've had a mapped ecu before with no external signs that it was mapped only when i opened it up could i see the daughter board.
