Camber plates and ride height

[hachi roku [86]]

Do camber plates add additional ride height (on stock shocks/springs)?



That's not an issue with coilovers, but I'm wondering if I go with camber plates and rest of suspension stock. I really need more camber for the track, as just camber bolts don't get me enough.


Thinking Velox / Cusco or similar price range. Raceseng seems to have a different construction but they are also twice as much.

Otherwise stock, I believe all camber plates raise ride height on this chassis with raceseng keeping the car the lowest. I think the change for raceseng is around 5mm or less but I could be wrong. I was very happy with mine but I understand they are expensive, I think the others are worth trying to get what you need.

How much camber are you getting with bolts? Two sets of bolts should be able to get you around -2.5 or so, you can also modify the bolts holes in the stock struts for more camber if you're desperate. Just making sure you are getting what you can out of the bolts, you'll still need them with camber plates to comfortably hit -3 to -4 and more.

AST makes a camber plate that doesn’t raise the car.

I had HVT camber plates that did the same thing but they are diacontinued.

Thanks! Seems exactly what I need. I tried googling for AST ones but now active hits. O wonder if they are still being produced? And why HVT discontinued? Seems really strange but it’s not the first time I see how parts for the twins are discontinued... *

I believe they use the same ones as the 04 Wrx.

I went to a Porsche event at Laguna Seca a couple months ago and talked to AST there who said these plates were for the “BR-Zed” so I assume they’re not discontinued.

HVT just went out of business in general.

Regarding camber plates: You want to get ones that don't rob you of much, if any, bump travel, *especially* if you are lowering the car.

I got Raceseng camber plates and Swift BRZ Sport lowering springs for my car soon after I bought it in order to do track days and compete in time trials. These camber plates do not raise the front of the car, if anything they might lower it. The Swift springs are advertised to lower the car 1.1" up front and 1" in back. With the camber plates my car was lowered 1.5" front and 1.25" in back.

The camber plates utilize a radial bearing to accommodate steering, which robs the front of ~12mm bump travel vs. stock. Combination of lowering and camber plates subtracted a whopping 2" of bump travel. Which meant the front was riding *hard* on the bump stops. Cutting the bump stops in half, and then to 1/3 original height helped the ride over potholes/bumps a bit, as did adding a 1/4" ring between front springs and spring perches to gain some much-needed bump travel. But the ride on the street was still pretty intolerable over the smallest bumps.

I'm going to look into other camber plates to see if any are available that:
1. do not raise the front end, and
2. do not take away bump travel.

Or I *might* modify the Raceseng spring perches to remove the radial bearing to provide more bump travel, letting the spherical bearing take the steering rotational degree of freedom. Probably not the best for spherical bearing wear...

My 0.02 on this, fwiw...

I've had camber plates that don't have a radial bearing, Verus Engineering, and it was the biggest waste of my time and money. I had the camber plates for a total of 8 months, 1500 street miles and about 10 autocross events before the bearings failed and developed axial play. The Vorshlag camber plates are a great solution as well that do not reduce bump travel.

Thanks man, good to know, I won't bother with that mod then!
So, do Vorshlag plates either:
a) raise ride height, or
b) reduce bump travel?

Raise height, do not reduce bump travel.

Vorshlag also has a set designed specifically for stock or stock style struts and springs which do not raise ride height.

How did they pull that off??

How much camber are you trying to get? You can easily get close to -3* with the right bolts depending on your wheel offset/width.

-2.5* would make me happy. Will be on 17x9 ET35 for track use next season.

I’ve got a pair of Whiteline camber bolts, mounted top, and can get about -1.1*, not more. What’s the right combination of bolts?

- bolts in both holes. (14mm SPC camberbolt 81305 in lower hole, and 16mm Whiteline KCA416 (same as SPC 81280) in upper). Worth together maxed out around -2.3 at stock height, around -2.5 if lowered.
But as far as track use is considered, imho worth dial front camber somewhere in -3 to -3.5 range. Just camberbolts insufficient for that though (but of course cb's -2.3 much better then stock 0dg camber). Camberplates or eccentric topmounts or eccentric front LCA rear bushings or slotted coilovers needed to dial more then -2.3 of camberbolts. Most go for camberplates.
