I been looking into these oem fd wheels to run with the hoosiers qtp tires.
my question is that i have found out that there are two kinds... ones that reinforced and ones that are not... what is the difference between the two and would i be okay to run either one on hoosier qtp's? any info would help thanks


these are the wheels by the way.

 

Mazda had cracking problems with the earlier non reinforced ones.

 

like i'll be getting the reinforced ones.

hmm any idea how i can tell which ones are reinforced?

 

There is a thread on this somewhere on this forum. I think you need the non-reinforced ones because they are the ones that will fit with the OEM brakes.

 

late reply but i figure i would post this and help some people out

^non reinforced, notice the shape between the stud holes


reincforced, notice the clear bell shape in between the studs

Can any of you guys weigh one of these rims. I would like to know how much one weighs. Thanks

 

I have both kinds. The ones with the defined bell fit with a 20 mm hub centric/wheel centric spacer. I just tried it in my garage.

 

Looks like almost 14lbs. Add about 2.5 lbs for each spacer.

Mazda RX7 FD3S Cast 16x8 15.4
Mazda RX7 FD3S - PFD Cast (Brittle) 16x8 13.8

They still require a spacer to fit the front Brembos.

 

Weighed rims on home scale( not very accurate)
Evo X rim with Advan 46 lbs
Rx7 with Hoosier QTP 32 lbs
Nice rotational weight savings.
Shootout tomorrow
I'm ready!

 

Spacer weighs 2 lbs

 

My 17" wheels and slicks weigh about 29lbs together (MT Moto Slicks). Looking forward to running at the track with them!

 

Shootout today I saw atleast 4 cars running them, Strictly Modified, Eric in a IX black car black turbo,a Dsm, and Me Ron G.

 

Mine are forsale now... come stock polish and is the reinforced ones... m/t slicks are brand new... only 4 passes.. that just a mile.. 1050 shippped. $1150with 20mm ichi spacers

 

got any pics? i am looking for a set.
