take photos of inside driveshaft loop mounts otherwise they might want carpet back out to see, 2 piece needs 2 loops? saves alot of tickets when you pick up the fush & chups
i wouldn't worry about any of that, i put a neo 25 into an a31, ran all the std neo elecs and maifolds etc on an r32 rb25de ecu, ran mint, have sold the car but know it's still going no problem 3 years later
next to the relay box in engine bay where plugs are, there's 1 down the bottom with to big wires that need to join together, haven't done a 32 for ages so can't remember colours etc
i've got 595 on the rear, they were cheap and were supposed to be for skidpan, not too bad dry, wet fine for normal driving, i'd take a kumho over a federal in general
if the tie rods were adjusted to same toe settings then the rack would be the same length so shouldn't change anything, what was the report from the alignment?, otherwise hey you say they're the wrong ones & the car feels crap, put the right ones on?
