Exclamation Need Help. Car wonders at high speeds

I have a 2002 WS6 with the following mods. SLP Flowpac, SLP ported and polished throttle body, SLP 85mm Maf (descreened), Pacesetter Long tube headers and TSP off-road Y. Reciently tuned and laying down 336rwhp and 351 torque. For the suspension I have BMR Subframes, BMR Rear lower Control arms. And the tires are BFG Drag-radials 315-30-18's on the rear and 245-40-18 on the front. At high speeds the car seems squirly. Kinda like I'm on glass. Everything was put on the car at the same time. So I don't know if its the tires or maybe the Lower control arms? Or what to do to correct the problem. Any help would be greatly appriciated. Thanks, Kenny

The drag radials aren't helping matters any. They may be the source of the problem, or at least a good portion of it. Other than that, I'd consider possible alignment issues. And, 18" wheels with low profile tires will wander (trammel), it's the nature of the beast to some degree.

When I lowered my tire pressure to 28lbs it seemed to help.

Will lower the tire pressure to 28lbs and see if that helps. Its set at 35lbs right now. I hope this will help. I just got these tires and rims and don't want to have to sell them. Thanks again. If anyone has any other ideas please let me know.
