I also have my MT 305/35-18 drag radials on and they made a lot of difference. I now have a usable 1st gear back. I slip the clutch off the line then hammer it. Car actually stays pretty straight now and hooks real good in 2nd gears. I may have an advantage over some cars as I had Rousch anti...

The Nitto 555R's are not much good on wet roads with high horsepower cars. I have them on my car now and they started dancing on me when I just eased on the gas in 3rd gear. The roads had dried up from the rain but apparently there was still same moisture down in the pores of the pavement. I...

I don't know how the Nitto 05's can be that great. I ran the Nitto's05's 285/40-18 on my 2011 when I only had 460 HP and it would spin hell out of them then. I am running a 6 speed with 3:73 gears and the car only weights 3400 lbs. Since I had the supercharger installed and the suspension set...

Sounds like we have the same problem. I am running 677 HP and 575 torque on my 2011 GT. I am running 285/40-18 Nitto 555R's at 22 PSI on the street and I literally burn them up all the way thru 3rd gear. I think I am going to get a set of M/T drag radials II - 305/35-18. Hopefully they will...

By the way, the M/T's are a drag radial. I am just concerned about any rubbing problems and how low I can safely go on tire pressure on the street.

I have Nitto 555R - 275/40-18's on 10" bullet deep dish wheels.

Breenspeed does the same thing except they do so much testing that they have tunes specific to how you have you car equipped . They will usually give you 3 different tunes for different grade gas or one for race setup. You will talk to them or email them what your car is and what modifications...

Yes, that is at flywheel. I have the rwhp also on my Dyno charts. It was 574 at the wheels and I can pick that up by changing to a 1 piece Aluminum drive shaft which cuts down on the rotating mass of the stock shaft. Don't need it right now. It is a handful as it is.

Yes, stock engine. It is set to shutdown at 7200 rpm. It runs like a raped ape. Need to get bigger stickier tires. Running Nitto 555R's now but they can't handle the power. Looking at some M/T drag radial II size 305/35-18's hopefully they will hold this beast down on the street & track. I can...

I would highly recommend the Brenspeed tunes. Bought a Steeda CAI from Brenspeed and got their tune. It woke the stock engine up quite a bit. I was also running Magnaflow exhausts. They wrote the tune to take everything about my car into account. I just came back from Brenspeed in Indiana. They...

Planning on putting m/t street radials II on my 2011 GT . I am now pushing 677 HP with 575 tq. It is a 6 speed stick with 3:73 gears. The size I am thinking of are 305/35-18 . Has anyone ran these and have they had any tire rub problems. How low can I go on tire pressure on The street. I need...

Yes, it is summer. In the 80's but constantly threatening rain.
