Cheapest way to get more camber on stock suspension
 

I have been doing a bit(lot) of motor sport and with the max camber applied using camber bolts -1.4 and -1.6 I'm getting way too much wear on the shoulders of my semis.

At the moment I am saving for a trip so don't have the money for coil-overs or some expensive solution.

What else is out there which will give me more camber on the stock suspension?

There are top hats for the front which will give you more camber and caster.
For the rears there is a bushing/bolt combo that can give you more.

Both are over $100 though I believe.

You could also ovalize the top holes on the stock struts.

what's a "semi"?

don't be so quick to blame camber.

excessive shoulder wear could also be an indicator of improper toe

and also aggressive driving. No amount of camber will save you if you are using the tire to scrub off speed during a turn rather than braking optimally.

^^ Could also be too low of air pressure too!

From the context, I'd say semi-slick. https://www.google.com/search?q=semi-slick

yeah i wouldn't recomend anyone running semi-slicks at the track while on stock suspension,

(unless it's A6s and you're autocrossing, but that's something else entirely). You're bound to run into these sort of problems of not using the tire optimally.

Too much grip on the stock spring rates will either need a TON of camber, or will do this.

IMO the only good option is to stop running slicks until you can get higher rate springs (good coilovers!) to control the body motion.

R comps love camber is general. I run high rates on my DC2 but still have shit tire wear because I've been too lazy and cheap to replace my new OEM arms with shit adjustable aftermarket ones. I get good wear in the BRZ at around -2 at stock rates but that's on street tires still, for R comps I'd want -3 or so front and close to that in the back.

Having said that I agree, R comps with stock suspension is silly due to the lack of body motion control. Two problems here, one is camber and the other is maintaining it...

Yes, I am talking about Semi Slick/R Comp tyres (or tires in 'American').

I run them as a separate set as I enjoy being able to do lap after lap without worrying about overheating them as would be the case with street tyres. This way, I can drive to the track on my Prius tyres, switch to the semis, run all day on the track, then drive home on my still road worthy Prius tyres.

On my previous car (a 2004 RenaultSport Clio a car which you'll probably be unfamiliar with. Similar car to a DC2, small, high HP NA 2ltr FWD which handled really well) I ran R comp tyres on stock suspension with -3 degrees of camber and they wore perfectly.

I added cheap coilovers to that and it completely ruined the car so until I have the money to do coilovers properly on the 86, I want a cheap solution which will give me around -3 camber on the front.

The Top hats will only give me an extra -0.5 (so like -2.1 total at the front) for $220AUD which seems a bit steep. Drilling holes in stock parts also doesn't appeal to me.

Any ideas approximately how much extra negative camber "1 lowering springs provide?

The camber curve up front is really mild, so you're going to pick up maybe -0.5* at most from a 1" drop.

Ovalizing the upper hole isn't drilling a hole, it's just widening the hole that's already there.

You should get more than an extra 0.5 from adjustable upper plates, but you could get some adjustable lower control arms (figure about $600+ for those), or you *could* run camber bolts in both the upper and lower hole, but I wouldn't personally do that.

My first choice would be to ovalize the holes. Lots of companies sell struts that come this way stock (Koni Yellows do on cars that they sell a full strut), and the KW coilovers come this way too.

If you want to be cheap about it, then listen to the suggestions. "Slotting" your stock struts is the easiest and cheapest way to get lots of camber in the front. Not a big deal, and you can pick up a used set of struts from somebody who went coilovers. Coilovers by themselves won't give you any camber adjustability, but they'll make better use of your "tyres". A Clio to an 86 is apples and oranges. If you track the car often, your tire, brake, and track admission budget will likely exceed anything you'll spend on a "decent" coilover suspension so you might just want to invest.

and like i said, one free modification is to not bomb into the corners so fast

if you know your chewing up tires, don't drive in a manner that chews them up... especially on a lapping day where you've got nothing to prove,

and if you're trying to prove something to somebody when 220 AUD is "steep," then you're just being silly
