Spec Twin?

[Twinz]

Do we know if SSC will require the lockout washers or not? Since we will all be on the same shocks, I don't see a need for the washers.

No they will not be required, it's part of the reason they were able to get so much camber out of the "concept" car at nationals.

Can someone educate me on these washers or point me to where I can read more about them? About how much camber can a SSC car get with them and camber bolts?

Read somewhere in the last 15 pages of the C-Street thread. Konis have a larger hole in the top slot of the front shocks so they could gain 1 degree more camber. Washers were sent out to fix this. It doesn't matter in SSC because you get camber bolts... the washer is irrelevant with the camber bolts.

First result when googling "koni brz washer scca"

No ideas how much you'll get as when it was happening in CS you only got one camber bolt and ssc will give you two, but back then people were getting -2 or more.

Edit iirc the washer/no washer is not irrelevant as you'll still be using the crash bolt in the upper hole and the spc in the bottom hole. I'd be surprised if this was enough to get you -3 which is probably what people would want so you'll still be asking the alignment guy for maximum negative up front.

I haven't bought anything from tire rack yet, but had a Whiteline eccentric camber bolt lying around when I installed lockout washers on my Koni's. For kicks, I installed the eccentrics first and measured. It was more than three degrees.

I personally don't imagine wanting quite that much camber.

Interesting so that's on the 'big hole' Koni's you got ~3 degrees with one camber bolt? If that's the case that's awesome if that's what SSC will be capable of, if it's not a camber challenged setup it's going to be surprisingly quick if the spec tire can keep up with the fast street tires (personally I bet it's BFG, they've been trying super hard over the past few years to make a name in amateur motorsports, but I have no tipoffs for that hunch), like faster than a lot of STX cars quick.

fwiw when I was first autocrossing I was running totally stock except Z2SS, Whiteline upper camber bolts and Raceseng camber plates and I was right around -3.2 up front and loved the balance of the car (more camber was too much front grip and I chased the rear, less camber and the front pushed), I'm a different driver now and with SSC you'll be able to dial in rear alignment as well for better grip than I had at the time, but I can't imagine you'd want less than 2.8 or so, I'd start with -3.0 if I were building the car and had that much adjustability and would plan on going up from there.

To put it another way, STX 86's seem to be playing in between -3 & -4 for front camber, and you can put all the spring and swaybar you want on the car to control body roll and they STILL want that much camber. Compare to softer lowering springs and I bet most SSC cars will be maxed out, but maybe I'm wrong.

Interesting. I haven't paid enough attention to realize that. Feels like a lot of camber for a street tire... but yes, I expect that the flexibility will be there.

Now if only they could do some other things to make the class really really interesting.

There are a few twins running around -4.5 degrees in the front as well.

At some point, the top of the wheel will have clearance issues with the stock-sized springs. I think the STX guys can run skinny springs on their coil-overs and camber plates.

I was told the sample car had about 2 degrees. There was not a lot of space between the top of the wheel and the spring/strut.

Sample car was running -2. At one point in development the owner did max out the front at -3 and change. Considering there is a bit of camber loss with travel, and the car is softly sprung, somewhere around the max is going to be close to the optimal setting. Can get away with less on asphalt sites.

Rear toe/camber setting will be the more interesting part of setup for the car, since I felt the Street trim of the car abruptly broke loose on mid to corner exit.

Also; hi. I will be running this next season. :P

I'm not convinced all that rear adjustable crap is needed unless that car is slammed. I could be wrong of course, but initially I think I will skip it. When I had my old BRZ on Eibach springs, rear alignment was not an issue.

Sugar Daddies are a hell of a gateway drug, I find.

The rear gains negative camber through its compression stroke. Doesn't that mean you would want less static negative camber to attain the biggest contact patch in a corner? I'm not well-versed in front to rear camber ratios.
