View Full Version : Getting decent width wheels for a Cosmo

After months searching for some 10" wide wheels for the Cosmo rear end. I've finally found some that will fit with a little centre bore modification and massaging of the wing inner lip. The Azev "E" in the Honda NSX fitment 10x18 ET45 is about the max size that will fit with 295 tyres. They clear the outer edge of the suspension arm by aprox 3mm and wing inner lip will require rolling or shaving back to get the tyre inside. The centre bore is slightly under size but easily machined out to fit. There not the prettiest wheel but at least they fit.

Car will be down there in the morning nothing stunning about the wheels. I picked up a second hand set that are pretty rough just to try fitment as its all trial and error with the Cosmo, good news is they fit so it will be either new ones or refurb these when i get chance.
Pete running R888's on the rear so i can't do a lot more as regards rear grip. Fuel issues are now sorted (major overkill now) so it just needs mapping for boost. But yes figures where higher than expected at 0.2 bar 7000revs which is where we where at when the pump failed.

Think you need to run twin Bosch 044's then!!:D

Just about Pete. two independant systems for each rail two feeds two returns two fpr. Bosch 040 for primaries and 044 pump for the secondaries. I've ordered pressure sensors for each rail so i can wire them into the haltec and if either rail drops below a threshold pressure it will switch the Haltec into a no boost map. So that should cover the risks of using a twin system set up.
