I'm trying to find two rims (for drag racing)...The requirements were that they be 17x9, lightweight, fairly inexpensive, and fit on my '05 Z (non-brembo).

Could you tell me if these will fit?

Could someone explain what Summit Racng means by "backspacing" ?

 

ok--backspacing is another way of describing "off set" ...

still would like to know if these rims will suffice

 

Mustang bolt pattern: 5 x 4.5 in.(114.3mm)

350Z Bolt Pattern: 5/114.3

Yes the wheels will bolt-up. You mentioned lightweight. All I see is the word cast. I assume that these wheels are 20 pounds plus.

 

rx7 stock rims are probably ab etter choice. They're not only lighter but being 17' they also have a few more choices of wheels. Im not sure if those are 17. Rx7 wheels are 13 or 16 lbs, depending on the year.

 

Are you talking about 93-95 RX7 wheels? If so, those are 16x8 with a 50mm offset Bolt pattern is the same, 5x114.3

 

Even better, more slick choices and less radius (which is always better)

 

Old Pontiac 16" (Gran Prix GrandAm) wheels work great for slicks/DRs as well. If you have Brembos you'll need a 15mm spacer
