Members Brian L. Posted December 3, 2013 Members Posted December 3, 2013 Hey Spec Z people! I am working with a wheel manufacturer to get a perfect fitment wheel available for Spec Z. I built a car recently for a customer and had to buy special custom ordered hub centric 20mm spacers to get the current Enkei RPF1's to fit right. The off the shelf spacers normally sold with them are hub centric to the car but not to the wheel which kinda defeats the purpose. I hate running spacers or lame plastic rings so I wanted a better option. Anyway, since I see no reason to run 10's in the rear, at least not enough to kill the convenience and cost effectiveness of running a completely square setup and being able to rotate tires front to back, the wheel would be... 18x9" Hubcentric, +15 offest (no spacers!), wide bolt whole bore for quick changes in enduro's, and cost would be on par with what we are paying for Enkei's. So who would be interested? Quote
Members Brian L. Posted December 4, 2013 Author Members Posted December 4, 2013 Sounds interesting. Details? What additional info are you looking for? Quote
kbrew8991 Posted December 4, 2013 Posted December 4, 2013 How about 18x9.5 square? because they'd be illegal on the front 16.1 Wheelsa) Any eighteen (18.00) inch diameter rim, with a maximum width of nine (9.00) inches front, and a maximum width of ten (10.00) inches rear may be used. b) No wheel permitted for competition use can weigh less than eighteen point five (18.50) pounds with the exception of the Enkei RPF1 being specifically permitted for competition use. c) Wheels must be one piece. (i.e. No multi piece bolted, riveted, or welded wheels.) d) Aftermarket wheel studs, lug nuts, and wheel spacers are permitted. Refer to Appendix A for recommended Nissan Part(s). NASA_SZrules_2013v1.docx Page 8 of 11 16.2 Tires a) The 275/35R18 BFGoodrich g-Force™ R1™ tire is the specified tire for the series. Optionally, the 275/35R18 BFGoodrich g-Force T/A™ KDW may be used for wet weather competition. Quote

FastNotFurious Posted December 4, 2013 Posted December 4, 2013 Agreed.... and Enkei makes a nice 18 x 9.5 with an offset that requires no spacers Quote
Members Brian L. Posted December 4, 2013 Author Members Posted December 4, 2013 Agreed.... and Enkei makes a nice 18 x 9.5 with an offset that requires no spacers Are they hubcentric? What is the model? Quote
scotts300 Posted December 4, 2013 Posted December 4, 2013 Agreed.... and Enkei makes a nice 18 x 9.5 with an offset that requires no spacers Are they hubcentric? What is the model? He is referring to the 18.9.5 +15 RPF1, and of course, they are not hubcentric. There are metallic hubcentric rings that can be purchased though. Quote
FastNotFurious Posted December 4, 2013 Posted December 4, 2013 And you can get 'em in black too If you like that sort of thing. Quote
jon819 Posted January 12, 2014 Posted January 12, 2014 Any progress on this with the new allowed 10 inch wheels? Quote
Members Brian L. Posted January 13, 2014 Author Members Posted January 13, 2014 Ok, since NASA has released the 2014 rules stating 10" wheels will be allowed up front, that is what I want to spec out for this Spec Z perfect fitment wheel. Again it will be 18x10", no hub rings or spacers required. Who is interested? Send me a PM with your email so I can send out more details and we can see about getting a group buy going! Quote
scotts300 Posted February 4, 2014 Posted February 4, 2014 If anyone wants a set of four 18x9 +35 RPF1s in black, let me know. Personally, I like the 18x10 +38 RPF1 set-up, but it does require spacers and I don't have an issue with that. Quote

Members Brian L. Posted April 15, 2014 Author Members Posted April 15, 2014 Any update on these wheels? Waiting for enough interest to do a group buy, or to convince Phil's tire Service to start carrying them . Quote
