I know the later cup cars ran 18" Speedline wheels and I believe these were fitted to the last RS's (model yr '93?) but is there documentary evidence? Not seen a contemporary road test, brochure or anything. Is there an update to the Service manual or a technical bulletin that covers this?
Not just being an anorak here - good practical reason.
Any ideas?
