I drove the Maxima all winter on some 245/40R18 DWSs mounted on 18x8 G35 wheels on shitty Pittsburgh streets after replacing my motor, transmission, and steering rack mounts/bushings last fall. It's running great and my steering and throttle response is like night and day compared to the last 3 years of racing it. Feel that V6!

It's got a slightly wider track and I've been getting used to the tire placement while driving around Pittsburgh and North Hills when I have the free time. I pretend all the pot holes are orange cones and I'll be ready for some RE71s real soon now.

I can't decide whether to use my 17x7.5 rims from my Fini for the RE71s, or switch up to the same 18x8s my all-seasons are currently on, but i'm currently leaning towards the 18x8s... Anyone have some 18" RPF1s they might like to sell? Any opinions on why I should stay 17"? -pc

P.S. Following Joe's 2016 WRX thread about tires and wheels. Since I'm probably running a slightly smaller diameter on my RE71s than 245/40R18 (i had 235/45R17 in 2015) does it make more sense to just go with 17s instead? I can still get the 8" width if I go with new wheels... 7.5 actually fits the front wheel wells better i think...

Can u fit 245/40/18s on the max? That would give you almost another inch of contact patch.  Not sure if you would get some rubbin' though.   And for what i have done over the winter is nothing! lol which stinks!!  probably be my same unmodified except exhaust and tires/wheels as last year on the S2k.

Yeah 245/40R18s fit perfectly but they are like 25.7" vs the 235/45R17s which are more like 25.4".

So every year I fuss over this, then I just make sure I'm getting something slightly better than last year. I had some 17x7" wheels with DIIs which lasted for two seasons and really felt solid compared to the OEM 15x6.5 wheels, but 7" rims are just too small for a tire that size.

This year I think I'm doing the 18x8s because that's what I've been driving and they look great. But at 48lbs (tire+wheel) does anyone think it's worthwhile (for me) to lose an extra 20# with lighter wheels? What if I just lost 20# myself? ;-) -pc

Losing 20 pounds of unsprung weight is probably better than cutting bacon out of your diet.  Less wheel weight means your suspension doesn't need to work as hard.  Also, let's not forget about rotating mass.  The heavier a wheel is, the harder your engine needs to work to get it moving and the harder your brakes need to work to get them stopped.

Oh, and I may or may not have just bought 8 tires and 4 wheels.

You can run 9" wide wheels in STX... Why not do that? 

As for the weight reduction.... Yes.  Do all the weight reduction.  So 20 lbs off the wheels and 20 lbs off you sounds like you've got 40 lbs you can lose!

Thanks for your replies!

Why not go 18x9 with 255/40R18 tires?

I've considered that. For STX 255 is legal on FWD. Competitively it probably makes the most sense, but I'm also trying to keeping a smaller diameter tire (25.4 or smaller). I think 255s could actually rub my e-brake lines on my rear control arms.

If unsprung weight is a significant factor, I expect diameter plays as much a role in lowering my effective torque curve in 2nd gear which currently redlines at 70mph (plenty of room for smaller tires). Although 30mph in 1st gear is one of my better tricks on those tight AutoX starts.

Aesthetically, the 18x8s I have on the front right now look just a hair too wide, and are frankly not wide enough in back. I even considered 18x7.5/18x8.5 because I don't think it would hurt my rotation too much and look better. But then tire rotation woes. Probably a bad idea anyways.

So I guess I'm pricing 18x8/5.25 rims with 35-40 offset if anyone knows a good deal new/used on some wheels that are significantly lighter than 24#. RPF1s anyone?

Mostly I prefer to keep my wheels under the fenders and maintain some semblance of stealth for some daily drivability. At least that's what I'm going for this year. You simply don't notice this car parked at the Giant Eagle. :)

(You wouldn't notice it in the grid if I weren't wearing a helmet. lol)

Howdy,

Run 17x9's with 255/xx-17 tires.  25" OD.  Plus cheaper than 18".

Now if I only knew someone with some cheap 17x9s they'd be willing to sell... :)

You missed mine.  They went out the door yesterday.  :-)

I guess the PM regarding the shittiness of the springs that come with the ISC coilovers doesn't need to be sent now....

For anyone else, cliffs.  Bought ISCs for the M3, car never felt right, rear bottoming, bounciness, handled different left to right, etc.  Changed all springs to Eibachs and the car feels wonderful now.  Decent dampers for the money, springs are absolute garbage.  Rears were going into coil bind on small bumps (visible on spring).

Perhaps that was the source of my popping/clunking in the rear?  If it didn't sell next step was higher rates and swift springs. I'll have to let the guy who bought it know about that.

Exactly issue we were having.  Car bounced like crazy, and crashed at any bump in the rear.  Finally changed springs in the Mustang and tossed the 550s from that car in the front of hers and it transformed the car.  Changed the rears after that, all the issues went away. 

Went with 550/700. Dampers handle the rate fine only halfway up on the damping.   Car even rides better.

Wow! Hopefully the person you sold it is going to bring it out to race (and that they're not nearly as good of a driver as you ;) ). In terms of shopping, do you have anything in mind? What do you see yourself driving opening day this year?

Hey, uh, Alex?  Remember that time I let you Scandinavian Flick co-drive my Mustang?  ;D

Dan, most likely I'll be in a vehicle suited a little more properly for the scandinavian flick than a 400hp rear wheel drive monster ;)

Remember those new wheels and tires I mentioned?  They weren't for the Mustang.
