The G8 Gets Major suspension UPGRADES | subframe is complete 

Do you by chance have a part number list for all the rear suspension parts you threw in - including the shocks? springs? This would be greatly appreciated.

See how it didn't lower much even with the lowered springs, because the BMR lower arms pull the lower shock mount in towards the diff 20mm. It makes the shock more vertical, lifting the car.

I could see these parts helping handling a ton, but seems like it'd make traction even worse. You want weight transfer to the rear, but with the new shocks/springs and all the poly bushings, in my head I imagine there being less transfer since the rear won't be squatting as much. I could be completely wrong, too. I'd trade traction for the better handling any day, anyways. My '09 GT will need some suspension love soon, has 141k and I use it for delivering medical supplies. First on the list will be front strut bearings/bushings.

Do it feel like you getting more power to the ground with the new set up?

Can I get a link to the parts used?
