I posted this to the suspension forum but:

Hi All,
I am about to purchase either a 540 bmw or lexus gs 400 or 430. I want to know how much it will cost me to have the lexus handling like the bimmer. I'd go with the lex but for its more sluggish handling. If I can accomplish this aftermarket for not too much dough, I'll buy a gs.

Also, if anyone has a gs for sale please post details.

thanks,
Zach

 

Braces, sways, springs and shocks are about $1500 + install. With that lot you'll eat a 540i (w/ sport package) for breakfast. My neighbor has a 540i so I know.

 

Zach,

msray is trying to sell his mint gs400 at a very reasonable price, it is under the title "am i asking a little too much". we just had an extensive discussion on his sale of GS yesterday...

just get the stuff that Bit recommednd, you can even get one item at a time untill the handling reaches your goal.

steve of carson toyota supplied the items at a discount. his name is SUPRATRD on this board

 

In addition to the suspension parts Bit recommended, don't forget the Steering ECU for another $125 or so. This stiffens the steering a bit.

 

Thanks for the info, y'all. What engine or other tweaks do you recommend to increase performance?

thanks,
Zach

 

Zach, many here like the Swift Racing intake with piggyback fuel/air ECU. $600+install I believe.

Also, many like the Precision Industries replacement torque converter (TC) which apparently makes the car put its power more effectively to the pavement. I think this is about $900+install.

Beyond that, Swift does make superchargers, but I don't know about the power increases and they're big dough.
