Coming up on 93k, TB,hoses,belts,LWCP & LCA bushings replaced, Blackstone report looks great, says to take the T6 to 5k, I'll still do 3.2-3.7 OCI's. LWCP does make a difference on the 5eat as do the LCA bushings.
My dash would rattle more during fall and winter, one stopper in drivers corner, dash rattle is completely gone. I think it may depend on car mileage and roads you traveled or travel to loosen the clips up, 3 V1 or 3 V2 in both corners and center should eliminate all dash rattles.
My DRS is installed in the corner, the black dash and the black on the windshield hides it real well. I can't express how much I love my rattleless car. My daughter even found my rear rattle that was driving me crazy too, it was the hanging center seat belt (wagon) latches, they need to be tucked into the cubby.
Just returned from my 12 hour one-way trip, back felt great both ways ( 1 year older too) yes I played the wimpy sport of golf and tennis again while I was there. I wonder if Tiger drives a LGT since he just had back surgery? Tiger and Federer are such pussies!!
When I arrived at my destination none of my Rugby buddies were around and couldn't find any tough mudders to enter so I opted for 7 hrs of mellow exercise. By the way, I've had back issues off and on my whole life, yeah sitting in ANY car for 4 hrs will make your back a bit tight.
Drove 12 hrs straight last year ( going to do again in a few days) with a few stops to pee and fill up. Walked 18 holes the next day and played a couple of sets of tennis too, I'm not a young kid either. What's wrong with you pussies?? Sell your car's and buy a Lincoln with a sofa in it. Like GT said, core work or learn how to stretch.
