slotting strut holes for camber

[3jcelica]

I know this sounds dodgy but I must say this is not for road use but 3j improved production on a limited budget.

Rather than go to the expense of adjustable camber tops can this be done? and what are peoples thoughts? looking for -2deg

I have already increase the front and rear track by 50mm so dont wish to go any further (dont think I could without arches) suchas longer arms etc

looking at additional stiffinfining any way to weld in a strut brace. Could I achieve as much as adjustable pillow tops?

[mullett]

Yes, you can do this for sure. But there are better options, like camber bolts. The MR2 ones allow about 6deg of camber, they're awesome. There might be a way you can adapt things like that in. If you can do a drawing, I can machine almost anything as well. Might be an option...

Thanks for the support, have to get me head around these camber bolts are these the whiteline ones you are talking about? are the adjustbale? and how do you adjust?

[mullett]

It's hard to explain, but if you understand how an eccentric lobe works it'll help. Basically the bolt goes thru an eccentric, which sits in a round hole in the strut. The bolt hole on the eccentric is drilled off centre, so as you rotate it, the bolt hole moves in a circle. If you looked at it in just one plane, the bolt is effectivly moving forwards and backwards, hence adjusting your camber. You adjust it by rotating the eccentric. It's kinda hard to follow without seeing it, I'll do a sketch if you like.

thanks for that I know what you are talking about, I would not supprise me if whiteline has these in there catalog for a AE86 which should be almost identical to KE70 have to check it out.

[mullett]

yeah, they should do. This will only give you about .75deg I think, any more than that and you'd need to enlarge the hole in the casting, and I doubt they'd make kits for that. Check it out tho....

Putting in an eccentric pin does the same job as having a longer control arm, so as you have pointed out that this is not an option, i dont think it will work in your case. If you want to move the pillowtops in, then you should look at drilling out the resistance welds on the strut top mounts in the body, removing them, and seam welding a new plate in, then opening up the holes where you require. This should be quite solid and will give you the effect you desire.

any idea if the ae86 ones fit an RA28?

[o_man_ra23]

Check part number for the lower control arm bushes... I believe they are the same for AE86 and RA28... Might have to look into this myself for my RA23.

Look into cold strut bending. It's a bit ghetto but it works. My mate got about 5-6 deg neg out of a bluebird strut till it snapped at the base! If you dont push much more than 2-3 deg, you should be cool. Perfectly legal and undetectable too. Undetectable as in no strut tops/rose joints etc...

[Norbie]

Strut bending is the way to go if you want a fixed amount of camber (ie no adjustability) and as mentioned only need a small amount of movement. It's very common in racing circles.

[EVOSTi]

its NOT legal, well not in NSW anyway but it is virtually undetectable.

[oldcorollas]

2deg is 20mm(ish)
the size of the original tops may mean that there is not enough space underneath to move the actual plate inwards that far. which is where the adjustables are good...

what you could do is get non-adjustable tops with spherical bearing and cut it down and slot your mounts, but then you may as well just get a set of second hand adjustables.. even if for another car, and cut them down instead.

[Steve-AE86]

The other problem with slotting the holes is that in 3J while the strut tops/camber plates are considered free, the mounting mechanisms arnt. Same as cutting area out of the body to increase available camber.

Sorry to destroy that one, but i would hate for you to turn up to scrutineering and being turned away because of that mod.

I ended up using coil overs so no strut to tyre rubbing and it allows me to get rid of the spacers so I can now increase the track to get camber so I am just extending my arms yeh.

O man RA 23, I don't think mullet is talking low control arm pins, but ones that go in the strut top. but I could be wrong
