I have a 2007 C6 with MN6, 3LT, Z51.

Mods as follows: Kooks 1 3/4" Headers, Hi flow cats, Z06 Mufflers with NPP in a Box, Callaway CAI and short throw shifter, Tune, 4.10s and hardened output shaft and trans brace, the all important 160 degree thermostat. Made 385 whp before the 4.10s and well before the motor was broken in (dyno'd with 925 miles on the car in 90 degree heat)

Driver mod has been performed.

I need tires. It is a nice weather car only. I have multiple sets of rims.

===============

Factory wheels and tires will be put on the shelf. They should make for a nice garage wall hanging/decoration.

I have two sets of OEM replacement rims to be used as follows:

One set will remain stock, get refinished, and on which I will mount R compound tires in stock or nearly stock sizes. Which brand, what sizes should I use that will not throw the car's computer into a fit? Tires for inclement weather don't matter - the dealer told me my car is made of sugar and would melt if rain water hit it therefore it has never seen rain. I want something that sticks the corners and vastly improves braking response. Longevity of tread wear is the least of my concerns because I drive the car about 3500 miles per year.

The other set - Tractionmonster mod on the front wheels with the modded wheels to be used on the rear with sticky 1/4 miles tires. I was thinking of MT ET Streets II in 305 35 18. Is this the right choice?

Future HPR mods - either H/C or ECS supercharger; still undecided.......
Future performance mods - brakes (lines and pads) and clutch; possibly Pfadt or LG coilovers but I remain undecided. Keep that in mind when the recommendations are made.

Thanks in advance.

After doing some more digging around, it seems that no one makes R compound rubber in stock sizes. Am I wrong?

If I am not, is the Nitto Invo the best choice for replacement rubber in stock sizes for high grip or is there something else that will fit on the stock rims that will do it better?

Kumho esta XS
Great stick wear fairly well.
I'm using them for track use they seem to be the hot tire right now in stock size for track & autocross. and work nice on the street.
for a real track tire you will need to go non stock, CCW wheel are the people to see about this type of setup

I have the Kumho XS's and am quite surprised at the grip(when warm of course). Whether accelerating or cornering, these tires stick.

I have a pair of Kumho XS 295/35/19 they have about 500 miles on them and are perfect paid $600+ sell for $375.

I have tried many tires over many years, Nitto Invo's are the best performing "all around" tires I have ever owned.
The ride my car exhibits now is simply amazing, wet traction...again, amazing....dry traction, if it is warm out they need minimal warm up to be ready to grab. cold out and you can warm them up for impressive colder temp traction.

I was looking for the complete package at an affordable price and feel I could not have done better.

My tires were mounted at Hunter and were balanced with a road force balancer, I run 32lbs of air in all 4 for normal driving.

Thanks for the information. Which tire sticks better in the dry is what I am really interested in learning. Wet is not my concern as the only wet pavement my car sees is the driveway after I wash it.

Anyone with more insight..................

I would suggest Hoosier D.O.T. P315/30R-18 drag radials. This tire hooks!

I cut a 1.53 60ft with these tires, and did it with stock 2.56 gears.

You can get 305/30/19 Toyo R888s that fit on stock rims and your choice of 245 or 255 in 18" for the front.

Also consider TOYO PROXES T1R

The best tire that I have ever owned.

Just recently installed a complete set of BF Goodrich G-Force Radials KDW's on my 2007 C6 Coupe. After five laps around Atlanta Motor Speedway, I am convinced this is got the best tire for the bucks. Besides, you never have to use any tire dressing on these.....The tread pattern is really sick to look at and kind of say..BACK OFF!!!!!!!!!!!!!!!

A good choicw w TRACTIONMONSTER'S . I prefer the nitto R555r2 compound as did many others. Cant wait to get track times 10's ?

moog5050

I went with CCW T10s in 18 all around and NITTO 555R 335 in the rear and NITTO invos in 255 in front. They stick great and no issues with traction control as there is an inch difference front to back. I really like the set up and they can be driven in the rain should you get caught.

dovervold

Kicklight, how is the road noise with the BFG KDW's? The only bad news I have heard is they have a loud growl at speed. What was your impression?

I'm running Toyo R888s and they're good tires. A bit loud but nowhere as loud as my Advans on my other car.

Toyo R888 is unbelievably GREAT.
I use them for a track tires, and for Auto-x.

They have a treadwear rating of 60.
I know of no other DOT tire this low.

On the track (when warmed up), they really stick like glue around the corners.

On Auto-x, they don't really need any warm-up... but if the course
is fairly long.... anything over 30 seconds, they REALLY come to life.

When driving on the highway, yes there is a bit of a whine, but it is not annoying to me at all.

Since you don't drive in the rain, there is no reason to be concerned about their
lack of GOOD traction in the rain...
just drive sensibly, and stay away from any standing water.

GTR-Z51

So what size wheels and tires are you running?

Sparo2

For the money you can't beat the INVOs. They're all i run now.
I cut consistent 1.860fts and even high 1.7s. I believe they're some of the best street tires out there.

kaislick

i have tried several and will not use anything but toyo r888. using the 305/30/19 and the 245's up front. love them on the street, at the drag strip and best of all on a road course. however they are not great if caught a long way from home in a downpour (last week, had to drive at 60mph on highway)

oldmansan

18X10.5 and 18X13 with 18/30/295s and 18/30/335s (Toyo R888).
