To Much Tire?

[Humble]

Typically tire heat for racing and hydro planing in the wet for street are big concerns for a light car with fat rubber. I think you'll be okay with a 265 on the rear for street and the tires look like they should evacuate water fairly well, so wet driving shouldn't be too bad.

As for shocks, I would try to find a set of koni or kyb adjustable shocks/struts. Even if you aren't going coilover rear initially you could also run a pair of qa1 adjustable shocks in the rear. For the fronts, I can't remember if the maxx strut uses a 75-84 rabbit strut insert, but if it does you can get a koni adjustable insert (8641-1048SPORT).

On a side note, I found the front springs on the maxx struts to be too soft and I eventually went with a 200# spring on my old street bug.
