If you choose the spring rates that are best for your setup, then that is the way to go. The problem is the damping on these shocks is pretty crude and they don't control the spring well, so you need to run a heavier spring rate so everything works. That's why I say oversprung and underdampend...
The setup on Viper differentials is a bit of a learned thing, but most good gear shops should be able to setup a rear end to not much noise.
A noisy diff does not really mean there is a issue or its going to fail. On the Viper gear noise is a common complaint as the rear end is mounted
directly...
The Paxton kit is a good system. I developed all the Viper kits in conjunction with Paxton back in the day. The basic package with the fuel system worked quite well on a stock
engine. It made good power, was safe and reliable.
Once you made any changes from stock, then changes needed to be...
I never had an issue with the Gen 1 door wiring. Sometimes you can just pull the wiring cover back in the door opening and fix the broken
wires, but I have always found it best to remove the entire harness and solder in all new wires in the section that twists back and forth as the
door opens...
I've found the BC product on the low end of the suspension market. It does give you the ability to lower your car but the shock does not really control the spring very well and
tends to be over sprung and under dampend. Product support is poor. A much better choice than Aladan's. You get what...
Your issue is the additional draw at idle from the added accessories. I found using the next size smaller alternator pulley fixes that.
You might need to downsize the belt a bit.
That was at the motor. It shows you how good those Gen 4 heads flowed, as they had to be stock to meet the A/stock Class.
The engines did have 12.5 to 1 compression and a long duration camshaft.
Just switching to E85 alone will not be worth it. You will need bigger injectors and a new tune, plus your range will be dramatically less.
Without much higher compression or forced induction, power gains will be small.
You should should expect about 50rwhp gain if the car has headers. You need to change the valve springs and
run the low bleed lifters or you will have issues. I suggest you upgrade the pushrods as well.
I have a calibration for that if needed, it requires a 180 or 170 thermostat.
