Camber options.
 
Hey guys wondering how I should get more front camber. I am lowered 1.2 inches on springs. Have 14mm cam bolts in the bottom hole and crash bolts in the top hole. Currently maxed out a -1.8 camber. Would like to achieve -2.5.

So the options I have come up with are,

Option 1, Run a 16mm cam bolt in the strut top hole in addition to the 14mm cam bolt I already have in the bottom hole.

Option 2, slot the top hole in the strut and continue to use the 14mm crash bolt in the top hole along with the 14mm camber bolt in the bottom hole.

Option 3, slot the 3 holes where the strut mounts to the body. However I'm of the understanding that camber at the hub is more desirable than camber achieved at the top of the strut.


Forgot to mention that I do not want to run camber plates as they are far too expensive.

Thanks for the help.

So my question is, should I replace the 14mm crash bolt that I currently have in the top hole with a 16mm cammed bolt and run camber bolts top and bottom?

Or should I slot the top hole of the bottom strut Mount?

Or should I slot the 3 holes at the top of the strut where the top hat mounts to?

Any help is appreciated. Thank you.

Get camber plates? Never used them but it seems like that's what they're for. Otherwise I believe the way it's usually done is another cam bolt in the top hole

find a different alignment shop. You should be able to get -2.5 from that set-up, or at least very close to it.

I dont believe option 1 will benefit any more than current. Option 2 could but I don't think it's necessary. I dont know that I would cut my strut tower in any way like Option 3

Thanks, that's what I was wondering. Everyone else seems to be getting more camber than me. I installed and set the camber myself as well as aligned it using the string method. I only loosened one strut bolt at a time and tried to find all the camber I could by loosening the top nut, pushing the rotor in then tightening the top nut. Then undoing the bottom nut, pulling the rotor out then tightening the nut. I think I may need to loosen both top and bottom bolts at once and push the rotor in at the top while pulling the bottom of the rotor out at the same time? Reason why I did it one at a time is cause I only have one set of hands. [emoji28]

Camber plates are much better than screwing around with bolts plus you have a lot more options.

Tcoat 10-14-2020 02:33 PM

DO NOT start cutting slots bigger in the structure of your car or strut.
Save up your money to buy camber plates and do it right or leave it as it is for now.

Why are you after so much camber anyway? What size wheels/tires are you running?

I was under the impression based on my reading that camber added via plates isn't as desirable as camber via the hub due to something called SAI? I don't really understand it, it's just what I read.

AutoX, tires are getting way warmer on the outside edge compared to the inside. The wheels are from the previous owner but they look to be 17x8 on 235/45 S04 Pole Position 280tw.

the bottom bolt is eccentric right? That means you gain camber by turning it not by pulling/pushing the hub. You got the first part right about adjusting the top bolt first.

also getting camber from plates is fine. Sometimes its the only way

Yes bottom bolt is an eccentric bolt. I'll try again and see if I get more camber.

Do you perhaps think it could be from my drop that I'm not getting enough camber? From my understanding our cars being a MacPherson design in front and only gains camber up to 1" of travel anything after we lose camber? So if I'm dropped 1.2" could that be where some of my camber is going?

I suspect you're just not adjusted properly. He's right about the eccentric bolt, you have to turn the bolt to change the camber position, not pull on the hub.

That could very well be it. I'll be double checking my work. I do remember rotating the eccentric bolt thru it's whole rotation multiple times and measuring the distance between hub and a fixed point to verify max camber. Thank you. [emoji106]

i dont blame you, i just looked at ftspeed and camber plates are between 300-400 USD. you might look into onimade camber plates. 200+25 shipping USD. Im not sure if you can use camber plates on stock struts. i know you might not ilke them bc theyre a stance product, but for what they do vs how much they cost...

just another option that you might not have considered...

Thanks for the suggestion! Glad you understand my perspective. I will definitely look into these plates, 200 is much easier for me to stomach.

That is Steering Axis Inclination. I does have SOME benefit is certain applications as far as scrub radius however when introducing negative camber that way the tires will most likely hit the struts

I use Pedders top mounts which are good for -.75 along with the 14mm camber bolts (bottom hole) and 16mm camber bolts (top hole) and have achieved -2.75 front camber (aligned by Alex at Burning Rubber in Oakville).
Using a pyrometer, the tread surface shows very similar values all across during 8-10 lap sessions at TMP. This with Conti Extreme Contact Sport 245-45-17.
Using Blox LCA's adjusted at -1.5 rear camber, similar even temps are found out back.
After about 6-7 lapping events these tires, which wear incredibly slow, show dead even wear across their width.

Appreciate the detailed response. One of my plans was to just run 2 sets of bolts.

Did you ever run the car with just 2 sets of bolts and no top mounts? If so curious as to what amount of camber you were able to achieve? Also are you lowered at all?

Gotcha, I just had a look at the strut to tire clearance. Looks like I still have several mm left at -1.8. Getting a little close though.

99 civics had double wishbones up front.

https://imageapi.partsdb.com.au/api/...TKVPEJbUCSnYS7

I wouldn't bother tracking with less then -3 degrees of camber up front unless I really wanted to destroy a set of tires. Competitive autox setups are around -4 degrees camber up front.

My old E46 was factory slotted at the top mounts. And I see plenty of autocrossers slot top mounts/struts.

You're right it's a scion and new struts are cheap. Some of them, like konis come with enlarged holes for more camber off the shelf already.

Slotting strut towers diy is less common, the drift guys do it but they fuck with geometry more. The tenth gen civic has slotted strut towers for camber.

You certainly could slot the strut, but you shouldn't have to with your goals. Grab another pair of camber bolts and go to a good alignment shop. More then that bite the bullet and get camber plates/coilovers, you'll want them to be competitive in class at autox anyway.

Edit reread your op, top hat is centered in the hole, you'd have to hack up the whole hole to do that. Don't do that. Don't hack up your strut towers, totally unnecessary.

Heres what i would have you do

keep the bottom oem bolt in the bottom hole, and put the camber bolt up top and push the top of the wheel in.

I have learned a fair amount about how people run double digit camber. while we are idiots, we're not stupid. they ALWAYS anchor the bottom hole with the bottom oem bolt. you dont want 2 sketchy connections. people running big camber will get their adjustment from the top hole, either slotting inward, or in your case with a camber bolt, but the bottom hole is ALWAYS oem, that is the anchor that we dont mass with.(im not going to bring up FLCA in this thread)

i know some track people use a camber bolt in bottom and skinny crash bolt up top giving you adjustment from both holes but somehow they dont catch flack, realistically its fine, and so is slotted struts, but who am i.

many people do many different things, different bolts in different holes, but i recommend having the bottom be your anchor. hey, im not a fan of slotting struts either, thats why i got the onimade camber plates.

with the oem bottom bolt in the bottom hole, and an eccentric bolt up top, that will give you camber that is appropriate for the ability of most track enthusiasts.

This is how the scca official ssc class gets their desired -3 degrees of camber but they use koni yellows that have an enlarged upper hole to help.

HaXx 10-14-2020 11:21 PM

im just going to go ahead and say for the record

dont slot your struts please

even big camber boys bash people for doing it the hack way, and boast having setups that are achieved properly by complete adjustable arms setups, namely raxerx fab.

ie: "are you on slotted struts?"
- "lol, nah bro, racerx everything"

subjective aside, it is objectively hard to pull off fender to lip static fitment on 50k+ springs. its not even about how it looks, its the fact that they are able to do it, and the work that went into it that is impressive. i mean, drop your car 4 inches and tell me if you are able to drive it.

Hey thanks again for the offer I managed to obtain more camber and have pretty much maxed the clearance out between the spring perch and tire. I can only fit a credit card in between. So I won't be requiring your expertise.

You sniped it man, I loosened all the suspension bolts and the strut mount, then I lowered the car on a piece of 2x4 placed on the outer edge of the tire to max out the slack. I got EXACTLY -2.5. Thanks a ton! [emoji106][emoji106][emoji106]

Thanks! I managed to get the camber I wanted with one OEM bolt and one camber bolt, albeit with the camber bolt at the bottom. Probably not as safe as what you suggested but I'm happy I was able to keep one OEM bolt.
