HunterCustom Posted March 10, 2021 Share Posted March 10, 2021 Hello, I’m looking to put some 12in wide rims onto my 72” 240z but all the body kits I find are meant for 10.5” max witch would be good if I wasn’t going to be putting a over powered engine into the car Quote Link to comment Share on other sites More sharing options...
AydinZ71 Posted March 10, 2021 Share Posted March 10, 2021 Wow 12” is wild! I don’t know of any standard body kits that will fit tires that wide. just a thought, you will be getting diminishing returns the wider you go for street tires. As in, 12in will not get you much more traction over 10in. Slicks are another story. is this for a drag racing application? Can’t think of anything else you would want wheels that wide on.

Nelsonian Posted March 10, 2021 Share Posted March 10, 2021 Ztrix.com also known as Reaction Research has both the "YZ" and "IMSA" kit that will accommodate 12" wheels. Quote Link to comment Share on other sites More sharing options...

In the glory days of 240Z racing, all the IMSA GTU road racing cars all ran crazy wide rear tires....something like 345s on 12" wide rims. I know you are talking about street cars, but I have always wondered if such wide tires were needed even in a pure racing application. They were relatively low HP cars....probably 300-325 HP...and of course such wide tires are invariably heavier and potentially less aerodynamic.

AydinZ71 Posted March 10, 2021 Share Posted March 10, 2021 @Nelsonian to the rescue! I wasn’t aware he had fenders for 12” wheels I just got an OEM FRP hatch from him. Great quality! @Ironhead yep it’s the street tires what get me suspicious. At some point, the added rolling resistance, weight, and inertia outweigh any incremental increase in traction. The tire compound will have a much greater impact bang-for-the-buck than going from (for example) 10-12” with street tires. unless of course this is just for aesthetics...

JMortensen Posted March 11, 2021 Share Posted March 11, 2021 ztrix.com IMSA fenders are wider than the YZ stuff if that sounds appealing to you. I have read that back in the day they ran 16x14 or 16x15s. I have rear flares that were taken off of the molds for Frisselle's car, and they fit my 15x14s like a glove. Always thought the BSRs looked a bit wider, might be where the 16x15s come in... Quote Link to comment Share on other sites More sharing options...
Perfect240z Posted April 23, 2021 Share Posted April 23, 2021 I have the old Jim Cook Racing(JCR) kit on my car. It’s obviously a look that not everyone is down for but slot of guys used this kit for drag racing back in the day since it could accommodate wider wheels and tires then just fender flares. The kits isn’t available like the ztrix kits but they do pop up from time to time. Quote Link to comment Share on other sites More sharing options...
