Follow up: Car runs great and very happy with the final look. There is rubbing up front under full lock with the 225-35/18 tires with 3mm spacers. Purchased a heat gun and will work to reform front and aft of wheel well plastic. More to follow on that. The car was only lowered a total of .75 inches although now looks like more. (Car originally measured 4.50" inches at the 4 jack points on the body. Now measures 3.75". Will likely go back to 4.00") I think I'll likely adjust the car back up ~.25" to give me more clearance on the front tires at the top as there is an occasional rub on bump rebound. This project had MANY little steps leading up to the final result.. But of course was all worth it everytime I look at the car.. Never mind the looks you get in traffic. :biggrin:

UPDATE: 10/21/05... Just some added info for those asking... The wheels are 18x8 and 19x9.5 They come with a 38mm offset, so you will need to purchase a 3mm spacer front & rear. If your rear brake pads are worn you may think you don't need the spacers... but you will with new pads. Order the H&R hubcentric spacers and have them machined down from 5 to 3mm. Or run the 5 in back. Wouldn't recommend any bigger than 3 in the front. Don't forget the front rims need to be center bored from 67.1mm out to 71mm.

ALSO!!! The best tire for the front of the car with this wheel is 215/35-18. No rubbing, no problems! MUCH happier with the 215 vs the 225 I originally had.. The rubbing with the 225s was actually on hard body points behind the fender liner, not just plastic. Maybe at stock ride height you can pull it off, but not even with a small .5-.75" drop. I did go back up .125" and have the car realigned... So the car is .625 lower with all said and done.

what kind of beer?

Doesn't it suck to be a perfectionist!?! :tongue:

Ahhh, the agony of owning a NSX, lol... :biggrin:

Nice wheels, I don't recall ever seeing/hearing about them. They look classy, nice fit & finish. I'm sure you appreciate them all the more from all the labor & effort exerted on this project!
 
They look great!! I got my RPM 505's a couple of months ago. However, yours look great with the car lowered. The caliper guard grinding was a biatch. The fit on the front is almost too close for comfort. Here's a pic of mine...........I love these wheels.

Great wheels guys, nothing like chrome,easy to clean and all the bling!


Got to clean it often or the brake dust will chew up the chrome. I guess it maybe good that is easy to clean then.
 
Super!!! :biggrin: Luv the writeup and etc and the results are spectacular. I'll never get tired of looking at NSX's! Mine, yours, his, hers, doesn't matter - they all look good. (well maybe that Fugly car with spinner hubcaps and the wing was..... :eek: let's say in a different category.)

I totally agree with you about Mark at Dali Racing. :smile: He's the best, and I've started buying all my parts from him. He takes the extra steps to see that you are happy and informed.

Enjoy your car!

Your car looks awesome in chrome. One of the few all chrome wheels that actually looks great on an NSX! Congrats!!

Yes the hubs do need to be milled (my wholesaler can do it) But I can offer these at a great price. See this thread http://www.nsxprime.com/forums/showthread.php?t=52609
 
BTW for anyone out there looking at tire sizes... I swapped the 225s for 215-35/18s in the front and am very happy. Not only does the car not rub, but it somehow feels like the front end handles better at low speeds. Go with the 215s. 225s rub in the wheel well... and connect with hard points on the body... not just plastic. And will rub on top if you are lowered at all on hard bumps on the freeway... 215s are the answer.
 
I've had my new 18" wheels on my 02 for about a week now. I'm running an 8" rim in front with a 225/35-18 tire the car is dropped pretty low - a little more than a finger's width between the tire and fender - and have so far had zero rubbing. The suspension is a Tein FLEX kit. I've purposely turned the wheel full lock coming out from driveways and parking stalls and have experienced no rubbing. Last night, I made a u-turn at about the fastest I'd ever make a u-turn and again, purposely turned the wheel all the way and again, no rubbing. My tires are S03's.

Not all 225 section-width tires will rub on all cars (mine is an example). Are those of you who are rubbing with 225's dropped even lower than I am?

The suspension upgrade stiffened the car quite a bit... more than just the tires alone... but the overall package is not by any means too stiff. Nor is it jolting or harsh. You can still ride over RR Tracks, etc and not get pounded or have any sharp body jolts. There are some bigger potholes, that do send a sharper 'thwack' thru the car... but very infrequently. I wouldn't go any stiffer than the bilstein and Dali springs that I have. But the handling is worlds better, with far less body roll. I have about 10k on the car now since I did the wheels & suspension, and am very happy with it... I am 35... maybe if I was 65 I would think it a bit stiff for day to day. But I like feeling the road.
