BMR's 300A Performance Pack 2015 Has Arrived

The flares are mismatched. The rears are completely different style. Front's look awesome. Rears need same treatment.

Why? Because RACE CAR!!!

I think it looks like it works, so therefore looks great!

the aero is great though, so they in turn look great

 

[Dubstep Shep]

I mean honestly, the only race cars that LOOK good are the ones with stupid big budgets.

It's a good thing that you are in Dallas, you can drive over there and let them know before they take it SEMA. Good catch, bruh.....

Thanks for those who have responded with their previous experiences. I have now decided to go a different route with wheel and tire set up. I just thought it was a balance as well as finding the right amount of rubber for the cars power level as well. Why have 345's in rear if it can't spin 315's? I'm understanding now that it gives you that grip for more cornering capabilities too now. I though it might be better too to save weight.

More rubber/grip is always better. The issue is, as you stated, also adding weight. It's quite a balancing act and there is no "right" answer. It's what combination performs best. If wider tires means faster lap times, then run 'em.

Or just get more power and then you can really justify wider tires hehehe.

Can't spin 315s? Hmmmm you sure you're in a Mustang? You don't want to be spinning anyway - sideways is not fast

My recommendation for non-competitive track days is to run a 295 street tire on an 18x10. It's the easy button for low (well, lower) costs, good longevity, ability to rotate tires for full use and there are a lot of 285 and 295 tires that will fit that wheel.

For competition use, first make sure you are rules compliant. After that, if you want to preserve the stock fenders I recommend either running the less expensive 18x10 with 295 tires, or the 18x11 with 315 tires. Beyond that you can really go crazy. And to address the "spinning tires", when you are exiting a corner at a very high speed and want to start accelerating for the straight, more tire helps a lot. Every time, without fail, we have added wider tires in the same compound we have dropped our lap times.

I am really wishing TSW made 18X10 wheels...

I didn't realize you could put a 18x11 with 315 tires on the front, with stock front fender's. How much camber is used? This must barely fit. Is a spacer used, how thick?

Usually on the heavier side. If you want 18x10s I recommend APEX EC-7:

Why would you buy those when you can get a custom fitted set of 18X11" for about the same price?

Hey, 2012 called!!! It wants its news on "315's up front" back! Only joking...but there have been 315's up front on S197's for a while.

To answer your question- yes you need camber. 2.5-3.0 degrees should do it. Swaybar endlink stud should be cut down. Slotted strut should be pulled out to maximize clearance and minimize camber at the knuckle. Spacer need depends on your exact tire/strut combo. For example...I know of a car with 315 V710's and Koni yellows that doesn't need a spacer. My car with 315 Hoosiers and AST's needs a spacer. Another car with MCS and 295 Rivals doesn't need a spacer...so it really just depends. With fitment this "extreme" you'll need to determine the amount of spacer needed for each discrete combo...we're quibbling over millimeters in either direction.

295 Rivals and 315 Hoosiers are almost the same size, btw.

When I put my car back together...I think I'll do a video on what needs to happen to fit the 315's up front...that question comes up a lot.

Because they can be rotated, they're lighter (just a bit, but still lighter) and he was looking for 18x10s.

They also look better, but that's not a fact it's my opinion.

TSW's rotary forged wheels are actually extremely light and pretty affordable, especially the interlagos.

You're right - they would likely weight 20.5lbs, but I still prefer to use an Apex wheel to a TSW wheel in a racing application. Maybe it's because I'm from the BMW scene and I've just heard the name more often or maybe it's because I just love the way the APEX wheel looks..... or maybe I own stake in APEX
