i have +15 offset and it doesnt rub, but im on stock height.

 

crappy cell phone pics for now

 

^
you need to get lowered asap!

 

i know! :[
shopping for coilovers and BBK now

 

05-350z if you ever sell I got dibs

 

There is a guy in the unofficial enkei thread with 305/30/18on all four corners

 

MAN I MISS MY OLD Z!!! I RAN THE RPF1 FOR A FEW MONTHS!!

 

Yes, that's me, but not on the 10.5 +15s. They are on the 18x10 +38s with spacers. No way they'd fit on the 10.5 +15s.

 

What size spacers are you running? Curious what the effective offset works out to be.

 

13mm and 15mm in the front both work. I was hesitant to go with the 15 because it looked close, but it worked.

10mm in the rear.

18x10 +23 front
18x10 +28 rear

Disclaimer: The V710s are not a BIG 305. They are about as wide as the oversized 285 Hoosier. I have a pair of 305/35/18 R888s I was going to try at some point.

 

Are these RPF1's polished silver or chrome? None of the venders seem to have them only Silver or black

Anyone know?

 

SBC (SPECIAL BRILLIANT COATING)
Breakthrough technology has enabled ENKEI to achieve a chrome-looking finish using synthetic coating and cosmetic techniques. SBC delivers a brilliant metal finish without the high maintenance associated with chrome and is used by ENKEI to maintain lightweight characteristics and enhance the finish of the wheels. All wheel weights are estimated.

 

bringing it back from the dead. thinking about getting this setup. anyone know how much the 18x10.5s weigh?

also what are the pros and cons of a neutral setup over a staggered

 

it's on there website...
http://www.enkei.com/rpf1.html#

 

Pro
Potentially a faster set up for the track
Less understeer
Depending on tires, you can possible rotate for longer life
Con
unstaggered 10.5's will have extra unneeded weight
Unstaggered tire setup will have low amounts of understeer (some people can not handle that)
10.5 is pointless up front when the offset suck for maximizing tire size for the wheel.

 

I like the idea that you can rotate tires and understeer is lessened, but the fit in the front worries me.

 

Just get something else, like a 9.5 front and rear. Simple solution.

 

I think their site says 19.7#, but I weighed one on a scale with .1# accuracy, and it read 19.2#.


Agreed, however, a 10.5" wheel will put down significantly more rubber - at least for a 285 tire - than a 9.5" wheel. Take a look (9.5 on the left, 10.5 on the right):



So although the 10.5 appears unnecessary and certainly heavier than a 9.5 (which can easily handle a 285 tire), you do get more rubber area from the 285 on the 10.5. I ran this set temporarily while I was getting a 10.5" wheel fixed, and it was the first time I experienced understeer in this car. I always ran the same size tire all around on the same size wheel, so this was the first time in recent history that I competed with more tire in the rear due to the wider wheel, and it was very noticeable. I'm back on 10.5s all around now with 285s.

As a point of comparison, the wheel in the back is also a 10.5, but has 315 rubber on it, which has even more contact patch than the 285 on the 10.5. Maybe I'll try those next!

 

Subscribing!

I am def. sold on 10.5 all the way around with 265 35s....

Looks great and seems to have some pretty legit feedback!
