I see on Machevo.com they're rated 19.4 lbs for 17x9 then I see threads with 17x8's rated at 15.x lbs...is the extra 1 inch width really 4 lbs? I'm looking for a 15 lb wheel in a 17x8...anyone know the true weigth of the 17x8 5 Zigen FN01RC?

 

According to http://www.xcceleration.com/wheel.chart.htm, 17x8's are 16.5 lbs. Just go for the fno1r's (without the "c") because they're forged. The fno1rc's are cast.

 

All of the following are strong and less than 16lbs in 17x8:
Enkei RPF1
Kosei K1-TS
Weds Sport TC-005

I have the 17x8 RPF1s for street. I crashed into a curb and it took a little chunk out but the wheels didn't bend.

 

I was looking into the Enkei's as well...right now its a toss up cause the more sites I check the more variations on weight I see, one site said 15 lbs for the 5Zigen's (cast version) so shouldn't the forged be even lighter? Can't picture that cast wheel being 15lbs in a 17x8...

 

5Zigen doesn't have the same level of expertise as the other companies I listed. I know the 17x9 is ~19lbs. I expect the 17x8 is at least 17lbs (cast versions).

 

expertise? i just wonder where you base this from. for as long as i can remember dori dori himself has always had a 5zigen on his racing suit.

as compared to enkei i feel that expertise is a sack of crap as we all know that the rpf1 flexes in a size that is supposed to shoe a certain width rubber. that's expertise finely failed.

the heavier 5zigen in 9.5 is heavier but also does not flex when shoed with the same rubber.

i think at some point we all have to compromise with either the weight factor or the price factor.

i just really wish that enkei didn't have this little problem.
