15" Brake Conversion??

[DavidKFla]

What kind of success are people having with the 15" brake conversion? When is it needed for these cars?

Well they make you stop less. so they are never needed unless you are trying to lose weight.

I was wondering how much more traction would be picked up by using the big sidewall 15" drag radial? Is it significant?

Jon and I both lifted the wheels off the ground on 17" tire

 

[vortecd]

I would be in it more for the weight loss

I cut 1.2x 60s on a 17. Beefcake has 315s in stock. You’ll hook on those no issue

I guess I wasn’t even thinking about traction for your setup. A 315 on a 17 and you will see a significant traction game. Night and day difference from the 305s

You can never have enough traction. Bad prep or even sub pare can change everything. I can't stress enough how much difference added AAD arms and 315s made to my car. The 1st launch I thought I was in a different car

If I remember there's a 50 and 35 series in the 315. The 50 is quite a bit taller than what I have now and the 35 is shorter than the 45 - 305 - 18" on it now.

 

[jonx96]

did they discontinue the 315 50?

 

[DavidKFla]

55s.. Super tall.

don't see them

 

[DavidKFla]

don't see them

The 55s are huge baloneys and the 35s are really short.

 

[vortecd]

summit has them in stock though

we are not talking 55s 315/50s

for me an @DemonSRT going from 305 street Rs to 315-60-15 radial pro made a big difference.
for me 305s 50/50 change of hooking, now hooks all the time.

When you don't want to be able to daily drive your hellcat and you are going all out race car to race into the 8's!

 

[DavidKFla]

The 35s are over 3" shorter than what I have now. That adds a bunch of gear which I'm not sure that it needs.

I'm not chasing 8s, just trying to get super consistent under any conditions.
