I've done it 3 times on this car to date.
2 x 4 is sketchy, double sketchy by yourself.
I've done 2 x 4 all 3 times and have all my fingers.
And I'll say it again, do not do springs alone on a non-DCC car. The base Sachs shocks are not able to keep the car out of the bump stops on a lowered car. Under heavy braking you will hit the bump stops and braking is compromised as well as it causing terminal, uncontrollable understeer.
That's bad when you're autocrossing or tracking. It can kill you during emergency braking on the street. Anyone that tells you otherwise is wrong.
I'm telling you this because I ignored the same advice and I installed APR springs on the base Sachs shocks. Just don't do it.
I now have konis, which are a pain in the ass to install, and would have 100% just had a custom rate redshift setup built for me instead.
I have DCC, which also sort of makes me hesitant. I really enjoy the DCC and the ride they produce. Also have heard rumors of having to re-calibrate the sensors for DCC and ACC? Why does this car have to be so complicated ha.
If I do pull the trigger on it, I was debating between VMR or H&R springs. Thoughts?
