NewestER DD 2012 GT500

594 posts in this topic

Finally had a moment to pull the bumper again and get the 13-14 headlights installed this weekend.  Had a harness made so that the swap was plug and play which was super convenient as they have different main plugs and turn signal plugs.  The harness also allows the DRLs to run like they should which is an added feature on these housings.  I dont care much about that, they just look 100x better especially on a black car due to the black housings.  If it was a white or silver car I woulda stuck with the 10-12 lights with silver housings.

13-14 on the left 10-12 on the right

I also took the time to hit everything that showed thru the now open grilles with some black paint.  Muuuuuuuch better.

Thanks...outside of maybe some wheels, which isnt THAT important, Ive done everything I really wanted LOOKS wise from the 13-14 refresh and at a steal to boot.  Im gonna hold off on much else till I can get out and see how she acts at the track.  I have a feeling that some rear suspension mods will be next as its a handful on the street traction wise.  I cant wait to see how it acts on the Mickeys vs the S550.

Maybe by the end of the year...not sure yet.  The TR6060's have terrible 1-2 shift issues (on all platforms they come in) and mine is no exception so Im gonna feel that out at the track.  IF I get enough grip to hammer the 1-2 shift clean then Im gonna start modding from there and could be in the low 700's pretty easy...if not knocking on the door at least.  If the trans isnt having it then I will tear it down, replace the suspect syncro with an upgraded version and then put in a new clutch while at it which will eat up the mod money.  $1500 TVS swap from a 13-14, injectors and a tune and Ill be in the mid to upper 600's on pump and can swap pulleys from there to go higher.  Or pick up a VMP Gen 2R or Gen3 and be all over the mid to upper 700's but sheesh, this is a true DD and it can already be sketchy on the streets so we will see!

I couldnt get away long enough to take advantage of the SUPER nice weather Sunday and hit up the TNT at the Hill but I did take a moment to make sure the Mickey's cleared everything ok on the wheels they are on.

I wasnt too worried but didnt want to get all the way out the the track and then realize they rubbed somewhere.  Nowhere near as sexyful as the GT was with them on but if they can get me some 1.6 60's like they did on that car then I will be a happy happy man.  Tues night TNT's start in April.  Cant wait to get some base line passes in and hone in the driver mod. 

Which reminds me, I finally had a moment a couple days ago to try some WOT 1-2 shifts on a dry, decently warm evening (50*) and was able to consistently grab 2nd without even the slightest grind or pause.  Ive read and now believe that spinning the tires is a major factor as is colder temps ( and stock clutch and plastic clutch line yadda yadda).  We will see how it goes at the track but I have more confidence now that itll be a non-issue with the Mickeys and a decent launch.

My friends c6 with the tr6060 is like you describe.  If it hooks, it makes the 1-2 shift.  If it spins, it won't shift.  The synchro just isn't good enough to slow down a high engine acceleration rate when you spin.

I know there's no sense in replacing those rear wheels.  But forgestar look like they would be a perfect match for the stock fronts.

Forgestars would look right at home with the factory fronts for sure.  It would look AMAZING on a full set of welds like yours :drool:

But for now Im gonna poor man drag pack it, knockoff Bullitts in the rear, 50psi in the fronts :lol:.  If I did anything it would be a set of skinnies to complete the setup.  Knock off some weight and resistance AND tame the sway on the big end.  Ide probably be more comfortable that way if I ever got out to Beech Bend with it then.

The quick and permanent fix for the TR6060 issue is a set of carbon synchros and they only cost $90.  Just have to tear the entire trans down to do em.  IF I have enough issues with it to start taking away from the enjoyment of driving the car Ill take the plunge as everyone Ive read thats done it, Ford and GM, reports back that its the best thing they have done to the car.

My friends c6 has the carbon syncros and they don't help.  He's on the second tr6060 and the first one got rebuild with carbon syncros and they didn't help then either.

I drove mine to work today for the first time with the "full size" front welds.  It was like driving on stock fronts.  The 18x7's with Michelin PSS's are maybe 6 lbs. heavier per side than the 18x5's with M/T sportsman fronts. They are still about a 10lb savings over the 19" stockers.

Really????  Damn :smirk:.  I HATE that I cant grab 2nd ever when I need to.  Usually if I spin a little pulling out of a parking lot or from a light I will short shift 2nd and get the grip I need no problem.  Not with this trans.  Itll do it, but itll make the nastiest grind noise and buzz your hand which pisses me off.  Lockout only happens at WOT and only when spinning bad so Ive only experienced it once but the grind is such a pain and it spoils any fun your trying to have.  Its honestly the only thing that I dislike about the car.  The 1-2 shift doesnt feel right to your hand EVER and it grinds when your aggressive with it.  None of the other gears are this way, they feel great and are there when you need them no matter what.

I honestly am not a huge fan of the factory SVTPP wheels that came on this car and would love to swap them for something else but just cant justify the cost just now.  Otherwise a set of black anodized Welds for both Street and Strip would the ticket!  Ill find something down the road at a decent price but for now Ill make what Ive got work!  Cant wait to get out and see what kinda fun I can get into with it.  Couple more weeks!

That's worse than his problem.  He only has issues WOT at the track.  You could very well need a syncro.  What kind of clutch is in your car, single or dual disc?  How well does the clutch disengage when sitting at a stop to get the trans into gear?

What 1st gear ratio is your trans.

2.97 First gear ratio I believe.  Factory clutch.  Its light and smooth from a stop, no chatter, no drama.  Getting the shifter into 1st from neutral quickly is a slight pain and the 1-2 shift is notchy/clunky and a decent amount of effort is needed to make it happen.  Installing the MGW shifter and changing the fluid to Mobile 1 Synthetic (per Tremec) helped a ton but its still semi-obnoxious.  All of my issues seem to be on par with the GT500 guys as well as alot of GM cars from what Ive read.  When it warms up outside or I give the trans a couple miles to warm up it gets better but is still noticeably notchy.  None of the other gears are this way, they are all smooth and more precise feeling if that makes sense.  Now, when dry out and warm I can be more aggressive off the line and hit 2nd harder than normal without issue, its mostly in the wet/cold that it grinds/scratches when shifted down low around a turn or when accelerating briskly and shifting mid rpm band.  I dont get to do many WOT 1-2 shifts with this car as 1st is useless at anything over 1/2-3/4 throttle so I have only a couple successful hard shifts under my belt, an equal amount of scratched shifts and one lockout to date.  The track will be the ultimate test.  IF I can get the shift without issue on a regular basis then I wont complain too much more about it.  If not...well I guess itll be back to the drawing board.  Im fairly confident itll be ok if I can get the launch down.

^ Can't get 2nd?   Autoswap yet?  :duck:

I'll likely not make enough power or want to be competitive enough (or want to spend enough $$$$) to want to do that.  Damned if 6r80 swapped gt500's aren't picking up unbelievable gains at the track but I still like rowing my own for the time being!

Do it! :hyper:

 

Not anytime soon.  Its $$$ and I still like being the master of my own fate :lol:

The 6R80 cars are unbelievable tho...shows the true potential these cars have.  Even relatively stock cars are going WAY faster than they should for the mods done.  For now Im enjoying shifting day to day and Ive noticed the warmer it is out the better.  Only track time will tell tho.  Nice thing is, I may have to wait a bit for the intercooler coolant to chill out a bit between runs but not to let the trans cool!
