TCE four wheel kit, sub frame connectors, optimized y pipe... who knows maybe some other stuff too.
If all goes well i might make the arrangements to have this done by late this week and might have myself an Easter gift. right now just enjoying the comfy ride of a big a$$ truck. What a shock it will be going from driving the truck to stepping down into the track beast.
can't wait.
