I would like to know what else I can do for my 01 Z-28 M6.
I currently have the following mods:
SLP Y-pipe---american thunder exhaust Two chamber--
85mm mass air-- SLP bellows---Holley powershot filter
SLP lid--- Mobile one in rear, trans, engine
I do not want to do power adders, cams or pulleys (( not that I don't want power adder they are just a out of my range ))

 

3.73 or 4.10 Rear End Gears , Short throw shifter??, STB and SFC,s

 

Do some suspension stuff, like SFCs, LCAs, STB... And headers, polyurethane tranny and torque arm mount (better energy transfer). Maybe even lowering springs w/ some new shocks??

I almost feel stupid asking this after being on this site for so long, but when referring to getting new LCA's (lower control arms) are you referring to rear LCA's or front?? Also, what is the purpose/advantage of getting new LCA's?? Are they shorter/longer/lighter/heavier????? Do they raise/lower the car???

I totally understand the purpose and benefits of things like SFC's and polyurethane bushings, etc., but I've never understood the reason for changing the LCA's.

If anyone could explain this to me (and to anyone else who was curious but too shy to ask) I'd appreciate it. TIA - Cap'n Pete

 

LCA are the rear control arms and they help keep the rear axle planted. The stock 'stamped steel' one tend to flex when a large load is applied to them, causing the rear to 'hop'.

 

What keeps the axle planted are the springs and shocks.

The LCAs transfer the power (accel and braking) from the axle to the chassis. Serious racers go for lighter LCAs with rod ends, to reduce unsprung weight, the flex of the rubber bushings, and avoid the problems with poly bushings.

A lot of LCAs with poly bushings are sold on the myth of the stock steel arms flexing (its the rubber bushings that give). It's a popular sales pitch.

See my mod list ... it's in the order that I added them. I agree with the other folks and think it's about time you started working on getting the power to the ground and keeping it there.
