Took it down a private rd over the weekend at 200 with cold brakes, no shudder. Then again with hot brakes and heavy shudder. I guess that means rotors?

I might spin it up on a hoist and isolate any drivetrain issue

It happens under power accelerating, then coasting or braking back down till abt 130

I was at Hampton Downs the other week and found that at high speed - over 170kph, the car starts to shudder severely, the shudder continues till speed has dropped to below 130. It possibly gets slightly more severe if brake are applied but not certain. I know my diff bush is stuffed. The car is an 09 G6Et. Has anyone come across this before? Not sure if it's driveshaft, brakes, wheels or something else. Thx

Hey Matty, I'm thinkin abt going down similar road to you. However I have seen you say several times u love the smaller turbo. How laggy is the 82? Is the gtx a better all round option? What RPM does yr turbo start to boost? I guess I really need to take a car with a 3582 for a drive.

Bump... my G6Et has just started doing this as well I was just installing a built in Bel STIr radar detector and ALP laser parking sensor. And noticed damp carpet under dash I guess behind the stereo. I noticed it again today when I was turning a long hard corner, my feet got wet. I had jst been through a car wash, but I assume it's the AC. How hard is it to get to the drain pipe and where is it?

Did you get use to the power easily before the gearbox started to give up? I just got use to the power of my tune really quickly. Then when I couldn't catch the little evo accelerating onto the motorway on ramp I figured it would be nice for a bit of extra broom. But not sure if I will get use to that as quickly as I have with the current tune.

Hmmmm... im not sure where to go... will do some reading on the 400 club. Might start prepping for that and jst get the gearbox built when it starts to slip. How are you finding the power you have now matty? 440 is it?

G6et '09, ID1000, big fuel pump, PW stg1 cooler, cat removed.

Am now well and truely use to my current tune (roughly 315rwkW) didnt have enough grunt to pass a modified evo on the motorway on ramp the other day. Wondering where to go next. I guess the next step is a new huffer. I probably want to steer away from needing a transmission build. But am not likely to ever take it to the strip, what is the trans good for? 400ish rwkw? We have just got e85 on pump in Auckland now. I guess I have just got to figure out what turbo to buy. I was jst thinking an F6 huffer, inlet delete, battery relocate I'll try and fabricate an inlet elbow out of ali. I guess I am getting close to valve spring territory too? Thoughts anyone? Thx

Am thinking abt invos

Sorry... G6Et, 320rwkw std rims. 245/40/18 currently. I figure the 45 might give a better ride, slightly better gearing etc.

I am thinking about increasing my wall thickness from 40 to 45. At the moment I need new rears, so was thinking about changing them to 45, then when my fronts are gone I would change them too. My question is... will running different profiles have issues with the dsc abs etc? Any suggestions or tyres that really hook up and arent too bad in the wet?

Took my freshly tuned G6 around Hampton on the weekend. Was great fun, though it did show a couple of limitations firstly the brakes on a big tank like this get so hot after a short while they just fade out badly and you just find yourself having to brake super early which is sad. So I will be looking at some sort of brake upgrade soon. Are territory brakes bigger? Will they fit? Also the engine oil would overheat after a couple of laps bringing a warning light on. So it's definitely lacking there too. Will look for an after market cooler to slap on. But well recommend it to get a new experience and learn how the car misbehaves when pushed. The best part of the day was people coming up to me and telling me I shoot flames!

Did it the other day, was easy as piss. Plus, gearbox has lost that lurch which is good. If anyone is thinking abt needing their zf serviced and places are quoting too much. It's a very straight forward thing to do. So dont be put off by nay sayers on here. I used GulfWestern Syntrans. Paid abt $200 aud for 20l. And just siphoned it into the fill port.
