99% sure the V6 front roll bar is the same at 18mm dia, can someone else confirm.
If so the kit is a good price inc delivery. Demon Tweeks ripped me off for £85 plus £10 delivery for the front alone and three weks del. Rear complete and delivered for £45.
I dont plan on getting under the car for another two months. Its accessibilty to the front roll bar U clamp bolts, one bolt one side is ok ish, theres no room to get much else in except a swivelling 1.5 degree ratchet spanner 13mm or 1/2"? from memory.
A word of warning if doing the rear No.4, it will need a 4 wheel alignment as the bushes cannot be offset, they are self centring in the trailing arm which will have to be repositioned by the three bolts.
Did my front wishbones drove around for two weeks then, front roll bar, weellater rear roll bar,psyched meself up one day and rear trailing arm.
The only hard part is removing the old bushes in front wishbone and trailing arms. Ooohaa err some dont like fitting the front roll bar 16mm jobbies on to an 18mm bar, get it right and you can clamp the bush, roll bar and U clamp by hand if need be to the mounting enough to get the bolts started.
Prepare for some grunting pmsl..
Most bushes are in two halves and a decent enough fit when tightened up.
You will wonder why manufacturers fit the rubber jobbies in with immediate feel of steering response and control. 2nd best mod on handling i reckon you can do, 1st would be quality tyres.
