4.33 gears

Anyone have these installed? How do you like them? I have a SS M6, farthest im going to go w/ mods are full exhaust and intake. Not concerned about gas mileage as its only a weekend car. Planning on a gear change this winter, trying to decide between 4.10 and 4.33.
thanks

When equipped with the manual transmission (M6) the SS comes with a 3.45 rear end and cruises at 1612 RPM at 70 MPH. By upgrading the stock M6 equipped Camaro SS to 4.11s you will realize an equivalent torque gain of approximately 20% or 84 lb.-ft. of torque and cruise at 1915 RPM at 70 MPH. By upgrading the stock M6 equipped Camaro SS to 4.33s you will realize an equivalent torque gain of approximately 25% or 105 lb.-ft. of torque and cruise at 2025 RPM at 70 MPH. We have found that the 4.11s are are the most popular gear for M6 equipped SS street applications.

So is the main issue w/ a 4.33 traction? I would like to hear from a few people that have 4.33's.

I have the 4.33's and love them. Ideally you would have a cam package and tune to up the RPM range of the motor to go along with the tall gears, which is why I went with them. I have some traction problems but that's to be expected with 476 RWHP and stock tires.

i have 4.10's and i love them, i wish i would have gone with 4.33's for now but i will be adding alot of power and i think it would be too high for any more power. if you keep car basically stock go with 4.33's.

On my thirdgen ls1 car I had 4.10 gears and ran 26" tires, with these 5thgens running 28" tires I dont think 4.33's would be too much.

4:33's in an M6 with 480 HP works great. Only power adder cars with extra torque need less gear. I shift around town at 2000rpm, 1st, 3rd, 5th. The gears really tamed my big cam and made the car easier to drive. I always take off in first, its not useless, but be ready to shift quick if you stomp it. This gear adds 110 ft lb of torque at launch. My 60ft went from 1.75 with 3:70 gear to 1.60 with 4:33 and more consistent. I can run 1.60's with 315/35/20 Nitto 555's.
Only added 300-400 rpm in 6th and about 1.5 mpg less at 70mph. Traps around 6,300 - 6,400 with 20" Nittos and 6,600 to 6,700 with 295x45x17 Mickeys.

I have 4.30s in my 9". They are great on the street. Good thing about a 6 Speed is you have 2 overdrive gears Still get 24 mpg on the highway with the AC on cruisin at 75-80mph.

I went with 4.10 gears and wish I would have went with 4.33. I could barely tell a difference. I made it 200 miles and shreaded the gears. Probably poor installation? Not sure but I had it done at a Chevy dealership. They are going to warranty the work they did and im going to try to get them to put in 4.33 this time. Car is n/a cam,cai,headers 479rwhp.

I had 4:10 and the pinion was wasted after a few months of street driving. Since the 1le released I bought 1 Le rear end from GM and it is great no noise and works well with road course. On 4:10 or 4:33 they are great for straight line and with a stock or mild set up you can not go wrong but i found on a windy road the 3:91 are a little better. ALso, on reliability More peopel believe the 3:91 are more reliable for street use.
