SP is for prepared STREET CARS. ST is for street cars with COMMON BOLT-ON and APPEARANCE Modifications.

You're going to be hard pressed to find someone that will agree with you that a larger radiator is a common street modification that fits the ST mold. Heck, just this past year, they took back the A/C delete rule for this very reason.

Ok, let's ask you this then... how would you write a rule in ST that allows aftermarket radiators, and have it fit the projected ST mold?

Remember, you have to have verbage in there that doesn't allow one to run one with less capacity or weight, because sure as **** I'd find the smallest radiator that I could run safely dropping 10-30+ lbs off the nose. It's only 2-3 min runs....

The new Fastrack has proposed language like that for SP:
http://www.scca.com/contentpage.aspx?content=78
Quote:
.15.10.I
Engine cooling radiators may be replaced with alternate parts subject to the following restrictions:
1) Radiator core dimensions (width, height, thickness) must be no smaller than the standard part.
2) Radiator must mount to OE radiator mounts.
3) Fluid capacity of radiator must be no less than fluid capacity of the standard part.
Alternate radiators may serve no other purpose (e.g. to allow a cold air intake passage)..
As long as there was no way to get a performance advantage out of it for Solo I wouldn't mind, but that's the rub. Ask Tom what he would do

Great! It looks like SP is where you would go just because of that added wording.

I just cannot see this being allowed in ST because it's not a common street mod. But that's just me.

Well I guess something like this: Stock radiators may be replaced with an after market unit, but must be done so with one of OE Style Design. The radiator may weigh more than the stock unit, but not less; if the after market radiator does weigh less than the OE unit, weight ballast must be added (i need to do some research to see how that could be done, and where).

Just threw that together quickly, but would work I think

I need someone to point and say "You belong in this class here ___"

Car 07 WRX

-TBE w/cats
-reflash/tune that has upped the stock boost
-KB SS with bushings
-F/R sways
-RCE Yellows w/STi Struts
-ALK
-Will have 225 tires as well

I ran ESP with just the TBE, EM and SS. Now that the rest is being added where do I go? I really thought I was still in ESP, but now I am told I should be in SM (where I will get toasted).

Thanks

Shawn

SM I believe, because of the ALK, and higher than stock boost.

boost is free in SP, but the ALK knocks you up at least to SM (I think some would argue Prepared )

If you consider the ALK a subframe mount then your in SM. If it is a suspension mounting point then you are in Prepared. However, IF you consider an ALK an offset bushing then you are in SP. The ALK is such a simple mod for our cars and major cutting and welding for others...

Wanna bet?

I would love run 2 piece rotors as the DS-2500 pads are not quite enough at the track. Instead I have to swap out to DS-3000 pads for the high speed stuff. I can't even easily run inexpensive Power Slot rotors in AS. Ouch $$$

you don't have to buy diffs to run in *SP. Sure they'll help, and a great deal, but WIDE tires and an insane spring rate is what is going to help you over the diffs. You can run the insane spring rates in ST but you can really take advantage of them in SP because of the race rubber.

Diffs are on my list, but the fact that the front diff install is almost as expensive as the diff itself, I'm holding off until probably 09 before dropping $4k on two diffs and the install. I'm focusing on wider wheels and tires followed by a race gas tune, both of which would be beneficial for TAs.

may be I didn't try searching hard enough but I didn't find what class you would be in if you removed the front U shaped subframe and didn't replace it with anything.

Well yes, but I think with the subframe removed that would be in prepared, not street prepared. Like FP, or XP something like that.

+1

I'm yet to figure out the difference in XP vs FP since the wrx and sti are both in fp and induction is unlimited as are motor swaps, iirc.

Hey guys, What are your thoughts about the Perrin inlet hose? I requires that you tee the pcv valve into the existing vent lines that run from the head accross the front of the intercooler. Is that modifying the pcv valve? It still is connected to the same system of lines, just not in the exact stock location.

The other option is teeing the pcv into the vent line that runs from the intercooler to the inlet hose. Does that effectively retain it's function along the flow path?

What do you think, legal for STU or not?

James

Your thoughts?

I agree the ALK subframe mount replacement part put you in SM. But... Superpro offers an offset bushing that IS legal for even Street Touring classes.

So does Whiteline. It's called the KCA-375 bushing.

SuperPro makes Whiteline's poly-bushings. They're just make them yellow instead of blue. Superpro costs about half.

When I bought mine, the Whiteline was marginally cheaper. Shop around. And yes, this is essentially the ST* legal ALK. Seems silly to me that we have to do it this way instead of just bolting an actual ALK into place. These are so much more labour intensive. But, I suppose, the part itself is cheaper, so it may just be a wash in the end.

the bushing is nice as it offers an additional .5 degrees of caster and a firmer bushing, but no change to the factory anti lift/dive like the ALK

Silly to us in the Subaru camp that have an easy bolt on suspension pivot that can be relocated to an advantage. Not so silly to a LOT of other cars that SCCA has to write the rules for. They have to cut, weld, and do other PIA things to relocate a pivot other than an offset bushing. So, we all get the same allowance.

Be thankful that Subaru used a large diameter bushing that can accommodate a lot of offset...
