Talking This feels like a new car!

Hey guys, finally got some pictures of my wheels and tires that I put on my car

I was really interested in the weight differences so here are some pics and specs:

Enkei Racing RPF1 wheels with Michelin Pilot Sport PS2 Tires

Front:
18x8
Offset: 35mm
Backspacing: 5.82"
Bolt Pattern: 5-114
Tire Size:225/40-18
Tire Rack Wheel Weight: 17.8lbs.
Tire Rack Tire Weight: 21 lbs

should be about -- 38.8 lbs

Rear:
18x9.5
Offset: 45mm
Backspacing: 7.01"
Bolt Pattern: 5-114
Tire Size:255/40-18
Tire Rack Wheel Weight: 18.6lbs.
Tire Rack Tire Weight: 25 lbs

should be about -- 43.6 lbs

I measured the new wheels and tires and compared them to the stock 17's and stock Potenza's with about 15,000 miles, the assemblies are a bit more than tire rack predicted but there is still a huge weight saving:

Front Stock:


Front After:


Rear Stock:


Rear After:



so the actual weight savings i achieved, not taking into account lost tread, was about 5lbs for the fronts, and 7.5 for the rears...

thats 25lbs of saved unsprung weight and boy does it make a difference...

as you can probably tell im trying to build up the actual pictures of the car, so heres a space filler where you can see the wider rear tires...



the rear "dish" (its really just a decent offset not a dish but it looks awesome):


the rear wheel:


and finally the car:






anyways, back to the whole "it being a new car thing" -- i couldnt put it another way...these wheels and tires have done a wonder for the handling and surprisingly just the get up of the car, you can feel the lightness, take turns faster and get off the line quicker as well - the tires are surprisingly hard to chirp, even in the wet, especially in comparison to the stock shoes

that isnt to say that this car couldnt use some, oh i dont know, lowering springs/shocks, sway bars, and a little bit more power from 'somewhere', but all in due time

as it stands, i love the stance, i love the look and most of all i love the feel!

I had the same feeling when I changed to lighter F-Sport rims with PS2's. Surprisingly the ride is even smoother with my current 19" setup vs. the 18" G-Spiders with RE050's.

Glad to hear you're happy with your new wheels.

One of these days, I'm gonna know what that feels like.

they say for every lb you save in unsprung weight (Wheels/Tires/Brakes) is like shaving 10 lbs off your car.

my volks are about 17+ lbs each (18x9) plus the tires were 24 lbs (Goodyear F1 Asymmetrical) each so yea, about 41 lbs all around with even wider tread all around (255/35-18 compared to stock 225/40-18).

Tires are the best $ for performance upgrades on most cars.

BTW, the car felt toooooooootally agile like I just put on skates or something lol

No more squealing in hard turns anymore either +1

I had RPF1s on my S2000...awesome wheels for the price with substantial weight savings.

One thing I hated about them though was having to fork over an additional $80 just to get the center caps, which don't come with the wheels.

They look naked without them.

Congrats on the wheels - and EXCELLENT choice in tires! I wish I had never driven on PS2's... I'm hopelessly addicted now!

performancewise you could argue either way. but for looks? 19s or 20s all the way
