[s-cars] Bilstein Sports Installed

[Southerlin, Russell S]

Mark,
>From rereading Igor's information it looks to me like he drilled the top mounts 5mm and slotted the fender holes and it got him about 0.7 degree of additional camber - see below. I don't know how much he slotted the fender holes but if you need 0.8 of additional camber I don't think you are going to get that much with just the mount being drilled.
 
I will test my camber and try to determine how much camber 4mm is equal to.
 
I went back and read Igor's write up as I remembered some info. on doing 5mm rather than 4mm.  In Igor's write up he does mention 5mm although the diagram/drawing he did shows 4mm.
 
Here are Igor's words/summary in his write up:
 
Amendment of 02-02-2001 after the suspension was totally redone.
All 4 tyres are at 35psi pressure.

Floor in the garage is tilted down from left to right 0.1°.
Camber before the mod (actual - adjusted 0.1° - in parenthesis):
FRONT L: -1.5°(-1.4°);    FRONT R: -1.3°(-1.4°)
REAR L: -0.8°(-0.7°);     REAR R: -0.6°(-0.7°)

FRONT: both top plates redrilled 180° and reversed. Additional Camber
found (plate moved 5mm outward). In addition the 3 holes in the top
mount were elongated.
Camber after the mod (actual - adjusted 0.1° - in parenthesis):
FRONT L: -0.7°(-0.6°);    FRONT R: -0.6°(-0.7°)
REAR L: -0.6°(-0.5°);     REAR R: -0.3°(-0.4°)

REAR: the 50mm x 12mm steel spacers were installed under the spring
perch
(courtesy of Eibach).

Ride height after the rear spacers were installed:
FRONT L: 365mm; FRONT R: 370mm
REAR L: 365mm; REAR R: 365mm

	Knowing Igor he did 4mm for a reason.  Two thoughts:  1)  That amount of offset was all he needed to get into spec.  2)  That is the max amount he could offset without interference from the curvature of the fender.  Do you recall if clearance was tight?

	 

	 

	Regards,

	Mark,

	I think what you are asking is if you move the top strut mount 4mm how much does this change the camber? I am interested in this as well as I need to do some more drilling and slotting of holes. Or do I take it back apart and do the Igor mod again - strut mount is looking like a piece of swiss cheese!!

	 

	I think you could easily test this yourself by simply moving the top mount 4mm inward (or any know distance and direction for that matter) and measure camber before and after.  This would give you the delta for a 4mm change. I should probably do this since my alignment is a screwed up anyway.

	 

	When doing the Igor mod I should have done the most offset possible (not sure what this number is though) this way I would hopefully have some additional adjustment for future wear if needed.  If you do the max offset allowed by the Igor mod then you will always have enough adjustment in the negative camber direction so why not go as far as possible in the positive camber direction.

		All I know is that my ECS plates are almost maxed out. Doesn't sound to me

		like 4 mm will do it. Same spring, shock combo.

		All,
		Thanks for the help.
		
		I got my car put back together last night although still need to do an 
		alignment. I am going to do a homebrew alignment to get it close. I am
		using a set of those laser levels to shoot laser dot onto wall.  We will
		see how it works.
		
		Anyway I still don't have enough camber adjustment on right side even 
		after doing the Igor 4mm offset - should have done 5 or 6 mm offset??
		As far a drop I have right at 362mm rear and 368mm drivers front and
		380mm pass front.   The front right is almost 0.5inch higher than front
		left??  Not sure what is going on there.  It looks like I will need the
		10mm spacer after all. Anyone know what could cause the front right to
		be so high?
