Hi Munter/John.
Thanks for asking but I still have the wheels, inserts and axles from my earlier SPR Proxy (standard) Bugeye Sprint. I demolished original chassis when car returned from Canada. You may recall chassis was a one-off aluminimum affair with a Solabotic mounted as sidewinder. Thought I would re-build for recent Bugeye Sprite Proxy but they went with the 1/29th body.
Wobbly inserts are a back-up however as Jim Clark's No.4 had Lotus 4 spoke wheels with knock-offs. I have a plan to copy these but just in case I have the former.
Chassis for Lotus 30 is another unconventional one-off so it will be interesting to see how it goes. I will try to post some photos soon. Still sanding rear tyres.
