Spec Twin?

In a few months, I'll take my car back to the alignment shop and I'll probably end up closer to 1.8 in the rear so I can use all of my tire back there.

Other than that.... looks good. I'm currently running zero rear toe, but I think their suggestion of 1/8" total toe in is probably more drivable for most people.... but... I like a loose car.

Thank you for your thoughts, which are very helpful.

I am interested in whether anyone has thoughts regarding giving the car some front toe.

Toe in or toe out? I wouldn't run toe-in on the front of a performance car. And I used to run toe out on the front, but after some people convinced me to go with zero toe, I made the change before Targa last year and loved how it felt. Still turns in beautifully and didn't feel as pushy mid corner.

Listened to the latest episode of SlipAngle with Heyward Wagner the other day. Some pretty interesting insight into the potential of SSC in other SCCA programs, consideration for its own classing in Time Trials Nationals and apparently even the Club Racing side of the organization is looking at the setup's potential for W2W.

Very happy to hear that the SCCA is recognizing the real potential of the platform as a do it all car. (Which is exactly why I was so outspoken about an oil cooler allowance )

So after all the hubbub about oil coolers, how many of us in class have actually done it? People were acting like it was a "must have" item for Autocross... but.. I just don't see it. Last year we did Targa in my car. We had track days mid-August at Charlotte Motor Speedway, Atlanta Motorsports Park, and Memphis International Speedway. I was running an OBD2 logger and most of the time the oil temp never broke 250. The only time it did was at AMP where I finished my session, pulled into the pits, and my co-driver immediately went out for her session without the car having a chance to cool down. It effectively did a 40 minute session with a slight breather for a driver change, and I think it may have gotten just above 260. Also finally got brake fade as she took the checkers and broke for Turn 1... so... it was getting some use.

I think a lot of people felt like an oil cooler was going to be essential for just autocross because of the hype, but I wonder how many people actually went through with it.

I don't know anyone who thought an oil cooler was at all essential for autox. It was for those of us who would want to run SSC and also do track days. Given the SCCA's consideration of the SSC setup getting its own TT sub-class it's fairly clear they saw the potential for the car to be a multi-discipline vehicle.

Even to that you can run track days without an oil cooler, I've done all mine up to this point without one, but it's certainly not a bad idea to keep your temps much lower. Particularly since people are routinely seeing temps around 270 on track without one.

Oil cooler was never essential, just something others wanted for track time. But after driving this setup a lot, I would certainly not want to run it seriously at the track. TT or otherwise.

I just know when the allowance was first floated, a lot of people started freaking out and acting like since it was allowed, it was something they absolutely had to have.

I've only had my FRS about 10 days, but generally speaking, I'm a big zero front toe guy. I want the car good mid-corner. I can adapt to turn in.

What I saw in relation to this was people being worried that it'd be perceived as necessary by many, which would increase the cost of entry to the class. Thankfully people seem to be halfway logical and realize it's by no means a must have part for the class.

I've known people to track on fairly similar setups pretty successfully. One friend I can think of who is decently quick ran on Konis, RCE Yellow springs, 17x8 wheels, and camber plates/control arms for quite awhile. He finally started hitting those limits and is switching to a proper coilover setup, but a decent aftermarket shock with lowering springs can do well for a lot of people on track. People are running similar variations in 86 Cup too.

Right. Which is why I said seriously at the track. Would be fine probably up until someone is decent at the HPDE thing, then will hit the limits of what the package can offer. I look at a TT class, which is what I consider taking it a bit more serious, and think it's a major turn off. Especially if Falkens have to be run.

Ah, missed the "seriously" part of it.

I thought of it mainly because the SSC package is mostly in line with the modifications allowed in Level 1 of Time Trials Nationals.

Toe out is what I had in mind. Thank you for your insight. Car goes in for its alignment this coming week.


I am starting to lean more and more toward the Tire Rack proposed settings.

I purchased the Subaru sandwich plate cooler thing to run as an oil cooler, as I do plan to track my SSC car some. Used the car at a lapping day last year (completely stock) and the OBD reader said I could get oil temps to 265F in 4-5 laps so I do see where people are coming from with the oil cooler thing (even though its completely not needed for autox)

I think i'd be considered an aggressive driver on track, so i'm curious to find out if this bumpstop thing sends me sideways and smiling or sideways into a tire wall
