[CUSTOMD]

building for a customer.
69 camaro vert..using the roadster shop full chassis..customer wants "the" largest wheel/tire combo on the back with a super deep front lip.
will be using the stock outer quarter panels (unless they need to be stretched which we can do).
also mini inner tub's with stock outer tub's (again we can change this to get this combo to fit)...not a drag or twisty car,more show and street driving.
any body done this combo/look/size?
any need to do info would be appreciated.
thanks
customd.

I originally had 340x45x17, so large diameter on a 68 Camaro on an 11 inch rim. But car had new rear rails and essentially tubbed. I have since gone to a 390x40x17

I think you'll struggle to get a 345 under without rubbing, even with a minitub and some outer guard massaging

A 345/30/20 is only 28" diameter, not real tall by today's standards. If the customer can afford a full Roadster Shop chassis, doing the tubs right will be pocket change.

No one in this country offers a 340/45/17 sizing. Is that a Euro-only offering?

Anthony Busacks 69 Camaro has a Roadster shop chassis with 345 30 20 rear tires. Do a Google search of "Project Silverback Camaro" there are a ton of details/pics of the car on various websites.
