Terra is right. Camber is around -3.2* with about 1/16" toe out. The only street driving the car sees is when it is being driven from the garage to the events. Tire wear is nice and even across.

 

Absolutely not. Not with 315 rears either, or 305 fronts for that matter.

 

Then you need to come into my subreddit and school some people.

Sounds like a bunch of people with low HP cars that don't have traction issues with skinny tires.

 

They are internet hardasses that know everything. I hope this thread school's them...

 

Seems clear that they've never owned tires that wide and are making blind assumptions.

When I had my 265-295/30/19 I noticed the car was much more nimble and steering effort was reduced dramatically. Probably due to a bit more stretch up front than stock but the increased width didnt have a negative effect as many would say. After all was said and done even with the larger wheels and tires (came from stock 225/245) I was more or less breaking even on weight.

Tire brand has a lot to do with it though... looking at specs on TR the weight difference between a 225/45/18 and 275/30/19 can be anywhere from 1 to 4 lbs, which is quite significant (see Sumitumo HTR vs Michelin PSS).

 

When I was trying to decide which wheel and tire size combo I wanted to go with last year I made this spreadsheet. I ended up going with the 10" front and 11" rear setup that is highlighted in yellow. All it takes is a little bit of research and measuring to figure things out. I had the OEM 18" chrome wheels and if I remember correctly they weighed more than my new 19" VMR's and these aren't lightweight wheels either. The new tire weights are the same as the stock size also. So my weights stayed the same or less, I have a lot more tire on the ground, the car rides and performs better, I can corner like a ****, and it looks better. That's my take on wide tires on a stock NA car...



Then plug all of those number into THIS! http://www.rimsntires.com/specs.jsp

This is how close it was before rolling my rear fenders. It rubbed going over the curb going in and out of my driveway and on big dips in the road going through intersections. Fronts have no issues.

You sir have found another way to do it right. Looks good. Mind sharing your excel template?

 

Thank you. How do you want me to share it? It's a Google Drive document right now. If you have a Google account I can share it that way. It's nothing fancy, what you see is what you get. I don't have any formulas setup in the spreadsheet if that's what you're looking for.

 

I'll PM my info later. But I'll try to make a template and share it. Thanks.

 

Ok so I installed the 275/30's on the front today. Removed the 255/35's, It looks way better. Perfect sidewall difference compared to the 305/30's out back. I guess I belong in the fat tire thread now. Lol

 

Oh yeah. Forgot the pics. I will post later. Car is filthy anyways.

 

Finally get to post here.









Front 9.5x18+15 - 275/35/18s
Rear 10.5x18+15 - 295/35/18s

Severe rubbing in the rear, fends were partially rolled to begin with. Now its at Motorsport Authority getting them rolled further and the car repainted. Ill post more pictures when I finally have her back.

 

Front control arms are not remotely BSP legal....just as an FYI. You also can't run a true rear coilover in BSP. Welcome to the wonderful world of SSM.

 

I know, but I wasn't going to tell the guy he was wrong about the class. But thanks for the heads up on the class I should be in. Now I can get magnets made. I was curious which class I was supposed to be in. I have replaced all of the bushings except the sub frame bushing I decided to go a different route with them in the future.

 

SSM is the land of 3 rotor, big turbo 2 rotor RX7's with full aero. I'm one of the faster BSP guys around, and the top SSM cars walk me like a dog.

Carter Thompson (former 350z guy!) won SSM last year in this:

Ouch! Oh well no turning back now. I'm not building it toward a specific class other than just building it for me.

 

Hey guys, I was thinking about getting a new set of wheels. If I settle on 18x10 square, what would be a good offset? And I like a fat tire but not too much sidewall. What would be good tire sizes? and obviously some tires are made much wider than others, is there one I should point more towards? Also, I would like to be able to clear brembos. Thanks!
