70 camaro wheel/tire questions...

[spinedoc]

I have a 1970 camaro which I am modifying using DSE deep tubs and a complete Ridetech Level 2 front and rear suspension. I plan on using 18 inch wheels front and rear.

Can anyone who has used this setup help me with tire and rim sizes? I need advice on backspacing in particular. I would like to use 335 on the back and am not certain how wide I can go on he front. Any advice would be appreciated.

Thank you.
