Addco offers a 7/8ths solid or 1 1/4 hollow.
Given the lack of clearance I had and still have between my 7/8ths bar I wouldnt recommend any larger.
Since the larger one is hollow its probably a little lighter while being just as stiff. Also note its much more costly.
Go to allshocks.com , iirc thats one of the better prices for bilsteins in the states.
They incorrectly list comfort valving as hd and hd valving as sport though. You'd probably want comforts or "hd" as allshocks advertises them.
They raise the car a little so using springs that lower it slightly result in stock ride height.
Lim is the lower intake manifold.
Gm didnt seem to do a quality job when casting them. You could have a machine shop open it up to 1.9" by 0.88- 0.89".
Seems to provide a good increase all around without sacrificing power at all.
My comment about the maf was in regards to the method used to measure air going into the engine.
Most dont have any issues with these cars.
The tps is the throttle position sensor. My point there was after a certain point, pushing the pedal down further will have hardly and percievable difference in power.
For the intake id suggest one of the two zzp sells with an amsoil filter that cheapo aem filter on ebau right now.
Not a fan of oiled filters. Sacrificing filtration for power isnt a good idea for any engine.
An exhaust mod would be a good idea. Like a plog or down pipe.
