What bits are you using for what?

All good am having another crack at it this weekend........will let you know how I go

[boostin]

No I mean what top hats, what springs, what shocks etc?

[DCVR]

swapping out v7/8 shocks for billies with Dobi springs. Needed to do top hat change on the billies. Noticed they didn't have washers in their assembly whereas the V7/8 ones did. Banged the billies in the BF and they were knocking like a mofo but it was more a metal on metal sound. Wondered if they were supposed to have thick washers like the v7/8 ones I have do.

Ok but what spring and top hat? BC pre-facelift? Facelift? GC/GF?

[DCVR]

I'm assuming the v7/8 shocks already in the BF are a factory shock and spring with a pre facelift 2 piece top hat............I don't have the history on them beyond that.

The billies are strait out of a B4 and had a 1 piece top hat but I didn't take any notice of the model. They had Dobi lowered springs on them. The BF tophat fitted strait up to the Dobi springs no prob

2 piece top hats are facelift. Put the top hats on the shocks without the springs and see what hits where, and where any washers are needed.

Yep am having another crak at em this wknd

I had to add a 4-5 mm thick washer under the nut when I fitted gtb billies to my series 1. The shaft on the billies had a shoulder that was bigger than the metal thickness of the top mount

Hey know this is old post got rear struts repalced in my pre facelift bc5,nd got new tophats,noticed starting to get a rattle when jit bumps,have replaced all rear bushes still doing it.is this same issue you guys are having.running low king springs and kyb excel g shocks,cheers

[Reuben]

The washer goes directly under the main top hat bolt. If you had it wrong, trust me, you'd notice, the racket from driving frank with no washers to the engineering shop was incredible! Are the struts new? That said, excels aren't inverted, so shouldn't get the dry lube knock of the STi KYB's and Bilsteins...

[DCVR]

yep what Rubes said ........a thick washer directly under the top hat........mine was completely missing

[johnston89rs]

So do i put it directly on strut under top hat or do i put it under big nut ontop that holds it alltogeather
