PostSubject: Will this Wheel fit?   Wed Jun 11, 2014 9:26 pm

Im looking at the Enkei Lxm 18x8 or 18x8.5. Obviously with the right 5x115 wheel pattern. And a +38 offset. Will it fit my 95 Rivi?

I think the 8" wide wheel should work with +38mm offset. For 8.5" wide, +38mm would probably work, too. There is a chance of strut rub with 8.5" wide wheels and certain tires, with larger offsets. I don't think +38mm is too large, but I haven't tried it.

Also check the center bore measurement. Read the early pages of this thread for info re: hub-centric rings. Good luck.

Where would I get hub centric rings specific to that wheel? Also the wheels are 245/45.

Don't know whether to put this in here or in the wheels that look good thread, so mods can move this if they want.

I'm looking at a set of 17" G35 rims that are pretty well priced. They're 5x114.3, but everything I've read says people run that size without issue on Grand Prixs and such. My main concern is that the center bore on the Infiniti rims is 66.1, while ours is 70.3. I tried looking for a spacer that would take our size down to the 66.1, but I couldn't find anything. I don't know much about spacers so I might just be looking in the wrong places. If such a spacer doesn't exist, could I just have the center bored out to 70.3 on the Infiniti rims?

I don't think you can do down in bore size using hubcentric rings; you can only go bigger. For example, if the G35 wheels had a 73 mm bore, you could easily fit to our hubs. Machining the wheel center is the way to go, should be no problem for a machine shop or competent wheel repair business.

Here's the alum bore spacer used in my Enkei wheels. Their bore is 72.62 mm ID.

I just called the machine shop up the road. The lady thinks he can do it, but she's going to have him call me back. I'm not about to ghetto rig it and take a router to them in hopes of making a perfect circle.

Should be easy peezy job for machine shop. Be sure to check for any interfering parts, and only machine the needed depth to install on your hub. Maybe buy an extra hub to measure from.

I have an extra hub I can give him for measurements. However, in my searches I found something entirely different....

http://www.ebay.com/itm/271703682943

Hmmmmmmmmmm....... They're like a half hour away, cheaper, bigger, wider, and will just fit without any worries.......

How many of yall are running 8" wheel width?

I am looking at wheels and tires and seeing options for 7 and 8 with a 17" wheel.

I am thinking wider = more grip so I'm leaning towards an 8.

Please advise.
Thank you

My American Racing wheels are 8" wide. With the tires mounted, they're about 9-1/2" wide....
There's room for more too.

Room for more you say? I am trying to get it right the first time. Not trying to drop ~$1k and not have it perfect! Will you help point me in the right direction?

I was looking at 17" wheels as light as possible with 8" width.

Should I be looking for 9" width wheels?

Charlie, just a suggestion since I know you like the biggest and the best.

Why not get a set of 18" wheels with a 32mm or less offset and beat me to the CTS-V caliper upgrade? The FRONT rims off of the GXP are a great option for this.......

Your options for a 17x9" wheel are going to be EXTREMELY limited. Most 17x9" wheels are RWD dedicated, or they have the wrong offset. I'd have to look at what the offset of mine are. I don't remember. I've got the 245/45's on there now. I think the next set of tires are going to be 255/45's if I can find them. Tire options get minimal when you start getting into "weird" sizes.

I want to go as light as possible with as much grip as possible. That happy medium is where I want to be. 18" wheels arent out of the question but I have been looking at 17s mostly.

I am not very interested in the CTSV calipers. Fbody calipers should do me just fine.

FWIW the GXP rims weigh about the same as stock and can run a 245/45/18 (pretty common tire size, might be cheaper this way). I haven't investigated aftermarket wheels since namebrand ones are expensive and no one knows for sure how well cheap ones will hold up.

Keep in mind 16" wheels and tires will be lighter (less unsprung mass). You will accelerate, and brake more efficiently once you gain grip, even if the threshold is lower. A wider, larger dia wheel/tire will grip better on launch, but won't spool up quite as quickly because of the added mass, rolling resistance, and aero drag. If you go larger than stock in rolling diameter, you also have to deal with decreased mechanical advantage (less applied torque), as the rolling diameter makes the final drive ratio taller.

Other considerations: 16" rubber is cheaper to burn through, and drag radials are less $$.

F-Body brakes should fit under 16" rims, but double-check your specific application.

Tire profile with 16" rims will be higher, so changes ride, handling and looks.

Wheel fender gap will be large with low-profile 16" tires.

Wheels and tire are always a compromise, until you run a dedicated set for the track. My 18s are 8" wide and work okay for track handling, help with brake cooling, and look good on street, but I honestly don't think I gained any grip or acceleration over OEM 16"s with good tires. And I hate paying for new tires ($800-900/set vs. $500-600).

For an all-out drag car, you'd want wide slicks up front, skinnies in rear, but that set-up is only good for racing in a straight-line.

A 245/50/R17 tire is damn near the exact same rotating size as a 225/60/R16. If you want wider, you can go 255/45/R17 to stay around the same tire height as stock. The only real thing that changes is the tire width and wheel size.....IF you do it right.
Going with an 18" wheel or larger and trying to keep the same stock tire height leaves you with "rubber bands" for tires, and ride quality is sacrificed. I like my 17's because it's a good balance of rubber/wheel IMO.

Upgade to 3.29 final drive ratio, then roll on 19"s if you want!

At that point, why not just go to 3.69s and 22"s?

Plan on doing the 3.29 with 2500 TC and other goodies once this trans gives up. Already saving up for it.. pirate
