im researching to find out if a 11"/315 setup with nitto DR's would be too much for my basic bolt on setup, i dont want to overkill it...

my question is, those of you with minor bolt ons, with 315 DR's, how is the traction? are they impossible to break loose? spin like a street tire still?

im deciding to get 9.5" wheels with a 275 DR or a 11" wheel with 315 DR's.

 

They are not impossible to break loose. Quite easy actually if you really wanted to. But its much better than any "street" tire.

 

The 315 should certainly give you better traction but I'd be careful with DR's as too much traction may kill your rear. Especially with an M6. You have a 98 right? Stock rear? How many miles?

 

With your basic setup you really dont need 315's. If I were you I'd look at a Nitto RII in 275x17. It has the same dr compound but with a reinforced sidewall. It will provide much better traction than any other street tire and will be comparable to a "dr". A dr has more flex to the sidewall and should provide slighty better traction. 315's of course will be better but will also cost you more money. IMO 315's on a non camed, non power adder car is only for looks and is overkill as far as traction goes. But they look damn sweet on there!

 

yes i have a 98 with 98k miles, thats what my question was, if the 315 drag radials would be overkill for my setup.

sometimes i think it would be overkill, but then i read stories of people still not getting traction with a 275/17 drag radial..

for instance, the other night my friend and i went to the track, and he just put on some 275 drag radials on his 17x9.5 zr1's, and was still getting 2.3-2.5 60' times.

 

you basically have the same mods as me, somewhat... you say its EASY to break lose your 315 nitto's??

like, how easy are you talking? just normal spirited driving around town, or doing like 4-5k launches?

 

If your friend is pulling 2.3-2.5 60' foot times with 275 drag radials, he cant drive. I pull 2.0-2.2 60' times with 245 street tires in 40 degree weather.

 

ya, he was getting the same with his old stock 16's... maybe it was the track, maybe he wasnt use to the tolerance of the DR's...i dont know, it was the first day he had them, so he was learning where the sweet spot is, inbetween bogging and spinning.

 

has anybody compared a 275 nitto drag radial to a 315 nitto drag radial? are they far from similar in terms of traction?

 

Yes, IMHO 315 DR's are a bit overkill for your setup for hooking but a 315 out back will certainly look badass. If you really want to go with 315's maybe a BFG KD/KDW or a Goodyear GS-D3 rather than a DR. You should be able to cut much better times than 2.3-2.5 60' on summer performance tires once you get good an launching. Just my opinion.

 

only problem with that is the price of tires, those GS-D3's are expensive in 315's... thats why i had planned on going with DR's, cheap and great traction. i just dont want to over do it and break something, or any of that.

 

OK, I gotcha. As others have said you should be able to cut fine times on smaller tires.

 

what about if a cam setup is next after wheels/lowering? lol

 

Sounds about right

 

You also need a good amount of power to go with that traction to break things. I'm running the stock 10 bolt w/373 gears. Its been rebuilt once and hasnt had trouble since. I put down between 440-450 rwhp and I dont drive it easy. I have 315x18's on it.

Reason for the rebuild was a pinion bearing possibly due to improper tightening when the seal was changed by the dealer. Anyway all the bearings were replaced and the gears, the auburn was fine. Its been good for a while now, when it goes its dana time

 

I just went from a Nitto 275x40x17 RII to a Nitto 315x30x18 NT01.
Before the heads and dyno tune the 275x17 RII's were great. After the heads and tune they weren't as effective. The 315's on there now grip pretty good. You are also going to have to do the BFH mod and pro'lly cut out your bumpstops as well as roll your fender lips depending on the offset you choose. 275's will be fine for you for a while even with a cam. Unless of course your draggin it all the time and then you'd be lookng at 15's and some hoosiers or something just for the track. Your a lot of mod money away from serious power yet. Might be better to save on tires and wheels now while you can.

 

good info guys, but all the wheels im considering are around the same price, and the nitto's arent much of a difference between 275's and 315's, i think the 275 is 144$ and the 315 is 175$ or something.

and yes i know about the fitment deal, ive researched alot.

any more suggestions?

 

What tire is that?

 

I mean just flooring it from a stop and letting it do its thing. It's gonna spin. But if you launch right, its a great all around tire. I can hook pretty good on the street, around corners they are pretty grippy too, the car doesn't widly slide around like it did on the stock tires.

 

What tire is what?
Also Nitto's or DR's need to be heated up for them to stick, even if they're 315's. Outside air temperature has a lot to do with traction and the Nitto. I doubt a close to stock fbod lights up a pair of dr 315's from an idle if they're warm and its 60+ outside. Rev the motor drop the clutch and get them spinning and yes you can spin them but they'll grip before you can run out of 1st gear and you wont spin in 2nd. I've got 440 rwhp and 315's and I have plenty of traction. Add cold air or wetness and spinning the tires is a lot easier. Its basic really. Tires are rubber. They are stickier when they are warmer than colder. The pavement is the same way and we dont even need to talk about moisture. Rain, dew.. it all plays a factor.
