2011 Tacoma issues !!

I thought my experience might help others out there. I didn't find any threads referring to my specific problems, so here goes.

Bought 2011 TRD sport w/ 40k miles for $26k. bone stock

1) I had an add a leaf installed w/ new Bilstein shocks n back and spacers w/ new Bilstein adjustable struts up front.

Tires are 285/70/17 open country AT 2 on stk wheels.

I had serious rubbing issues and vibration from 45-55 mph. The knuckle heads who installed the lift said it was the tires. 4X4 mudd connection in LR AR.

I left there and ordered spidertrax 1.25 spacers and the problem went away immediately.

2) After the lift/ spacers were installed on the truck (as I would turn to the right on occasion at different speeds) it began to vibrate violently as the brakes seemed to surge and would nearly pull me off the road.

I called a customer of mine (who is also a certified Toyota tech) and he told me to disconnect the speed sensor wire from the upper control arm. Problem solved

3) seating comfort is horrible for long periods of time behind the wheel and for the passenger (my wife). is there another seat out of a different vehicle that will bolt up?
