STF questions

Couple questions about planning my 3 setup for STF.

1. Was there a possibility that I could have ordered my '08 Hatchback Sport (sunroof, power options) with no a/c? How about with no rear wiper?

2. Is the Whiteline offset front LCA big bushing STF legal? It was ST/SP legal on my Evo, but only because of the way the LCA and bushing interact. But I remember reading that it was not legal on the Subies. The design of the Subie is very similar to the 3.

Here is a pic of my Evo arms with an offset bushing for more caster. These are spherical, so not technically ST legal, but the design is legal if it were poly.



Anti Squat/Dive was achieved by spacing the bushing up or down in relation to the subframe, which I know isn't ST legal because it technically moves the mounting point. And for the same reason, I question whether the Whiteline + caster bushing is legal, even without anti-whatever.

May have some more general STF questions that I'll add to this thread.

Thanks!

1. The 2.3L came with A/C as standard equip across the board so A/C removal not an option. Couldn't tell you for sure on the rear wiper, but I'd venture to say that it was standard on all the hatchbacks.

2. This one appears compliant with the rules. If you want to go offset, this would be a safe bet imo.

I have those on my 2008 and I'd say it was a waste. Made no difference. Get camber. Lots of it. Over 3 degrees up front is a requirement. I was at 3.8 and that was about the point of diminishing returns. 3.3 or so seems ideal.

Agree here. I was doing well at -3.5 degrees, and recently went to -4.3 or so. Times seemed to slow down, much harder to launch without too much wheel-spin. I'm back to -3.5. Trying out tomorrow.

Question.....anyone here find the need to do adjustable front sway bar links? In readjusting my camber yesterday I noticed a significant misalignment of the two front sway bar links. I'm thinking I *need* some adjustable front links.

(Related question......needed in the rear?)

If so, any used ones out there for sale, or, what's recommended for quality and reasonable price? Corksport? Whiteline?

Thx........

-3.5 to -4.3 with just corksports and a modified nut?

Hoping I can knab a used hotchkis bar soon, and I'll probably just replace my endlinks while in there. Also interested in opinions.

Well, if I was choosing over what is available to buy this week, I'd say the ZII Star Spec or RS3 Version 2 are pretty safe bets.
