As EVERYone ALWAYS says, if you want RWD, buy a different car. That whole "wish it were RWD" bit gets pretty old. Buy a G8. And a spoiler that adjust with speed? Seriously? Go buy a Crossfire, or a Porsche, or hell, save up and get the Veyron. HUD? Get a Grand Prix or a Vette (OOOH, then you get RWD TOOO!!!), and as for the Ram air hood, they make it, and it would be easily functional if you cut a hole in your airbox lid.

GM already showed up how to make an AWD w-body with the orginal G8 concept car. it was a 2 grand prix that they put a V8 and the Versa Track AWD system which used the 4t65 tranny.

There are a couple things I would like developed.

One thing is a nice alternative to the GM Racing Torsen Differential. It's $1300 which is outrageous compared to other trans diffs. Despite the price it is the only diff on the 4T65e market that is worth owning since it is gear based and not clutch based like some of the other units available. Since I plan to daily drive my car I need a design similar to the GMR diff or else I can expect a bunch of metal in the trans pans from all the grinding.

Another thing Id like to see suspension wise is a legit set of Lower Control Arms. ZZPerformance made a tubular set but they aren't the quality I was looking for. The way they were designed was very poor, and unsafe. Its only a matter of time before they snap and end up flipping someones car and killing the driver.
A guy named Ron Vogel would modify the stock LCAs and well new Moog parts into them. They were a legit upgrade to the stockers, however, he no longer makes them and doesn't share his secrets.

Finally, GM Racing needs to start making 1 inch chains for the 3.29 gear set again. They can't even be found used for anything less than $1000. The price needs to drop, its simply inflated due to it being discontinued. There are 7/8 and 15/16 chained gear sets, but they will stretch over time and break. The GM 1 inch chain never had a problem with stretching.

The trans is the weakest part in the W-Body platform. It has some nice hardened parts already designed for it, but an alternative, cheaper, torsen/quaife differential and a gear set chain that won't stretch is a must.

A nice set of LCAs would help our FWD platform stick better and launch quicker which ultimately reduces 1/8th and 1/4 times, especially the 1/8th which is growing in popularity.

Thanks,
Martin

Like a Trans Lock?

If so, there is a discussion on grandprixforums.net about a potential trans lock for the 4T65e

I would love to see a manual tranny made for our cars. that is the only thing i would change from stock. is the manual tranny option. but i would also like a supercharger. the sound you get with the cai was great and the look from people when they heard it out of the big car is priceless. that was the best thing bout my 04' gtp comp g. as for the people that want rear wheel drive cars they should sell them and buy either the gto or the g8.

It'll probably get recalled for some sticky gas pedal or other stuff breaking knowing the Japanese cars these days.
