Even with shock extensions that raise up the bottom of the shock 1.5"?

What gap to you have? Also, what tire psi are you running?

Currently with 4 turn on the TBs, I have about 0.5" gap. I am running about 42psi as I found this to work best as it's just enough to not feel the drag of running low tire pressure.

I think OEM settings might rely on the bump stops and not soley on the spring of the TBs for bottoming control. Once you crank the TBs to allow for a ride height increase, now it's sitting soley on a spring of TB rather than a combination of the cushioned bump stop and TB. A tighter wound spring seems to cause more of a bounce affect.

I am at the best it's ever been on the front suspension. Understanding it better keeps getting me closer and closer to a factory ride with cranked up TBs.

BTW, I owe you a sale on an item...

Reason behind it is I ended up calling True Tech to see if they could fix the bushings in my SMA trailing arms. He said he could, but I need to send them to him to have them modded so the new bushings will fit.

Rather than wait a couple of weeks to get them back and not having a vehicle to drive, I ended up buying another set from him to install now and he will fix the SMA ones for no charge. He did not want to sell them to me without going through you, so he charged me more for them than you sell them for.

I hope you understand....I had quite a bit invested in the SMA ones so this was my best option.
