I've been away from the Solo2 scene for the past few years,but I'm going to give my X a run in the stock class this season.Not much to play with in stock class I guess,but any setup tips or hot brands of parts would be great.

I was going to try out Hoosier R-comps,unless there is another hot brand I should look at.

Can anyone suggest a brand of shocks?

I have a set of Whiteline sway bars and I'm allowed to change the front.....any advantage to that?

 

For 2012, you can actually change either the front or rear bar (but not both).

Hoosier A6 is still the hot tire to be on. I'm not sure what size you'll want to run, but I'd imagine at least a 265. (I know the F-Stock Mustangs run a 295/30/18 on 18x8.5s, so that or a 285/30 might work).

 

I'm actually a bit nervous to change either bar on the X for fear of screwing up the handling.Has anyone swapped only one bar?

 

I wouldn't worry about messing up the handling. Either bar will do wonders actually! I'd probably still swap the front bar just to help keep the crappy camber curve in check.

I'd run the 295 hoosiers.
The stiffest shocks you can afford.
The lightest wheels you can afford.
I'd run a dump from the rear most cat.
And round it off with a harness.

Naturally you want to get as much out of the alignment as possible.
It will be a fun car and will certainly do well at pro's. But I don't see the car catching the S2K's.

 

Does the X have the same "rear diff assembled for quietness not for performance" issue that the IXs have?

What size are the stock X bars?

I was kinda thinking after the swaybar allowance passed that an IX with the OEM camber bolts, a rear bar, and a rebuilt rear diff might be pretty fun in BS, but I'm well past that point...

 

That diff mod isn't legal in stock unfortunately.

 

The front bar is the best bang for the buck?



Thats what its all about for me this year.......fun!(demo/fun run ^ from a few years ago)

 

I would do back to back testing if you could. But I would start with the front bar. Shocks will be huge too. Get lots of rebound and lots of compression in them.

 

I call BS on that! The service manual shows the assembly with the correct plate arraignment. So technically the way they come from the factory is "illegal" per the rules....unless there is some TSB or something that shows the "reduced noise" version.

 

Just curious.....what is this diff mod anyways?

PS I have no idea what the stock X bars are.

 

nonono, that's just a 8/9 issue from some gypped old rear diff we got out of the old evo3.


the MOD isn't legal (TRE, etc) but rearranging the plates back to FACTORY spec is 100% LEGAL


^ this is right. factory misassembled. no one can say anything when the proper arrangement of plates is in the OEM service manual.

 

This is exactly what I thought.

 

Does that apply to EvoII's as well?


Now I'm really interested!

 

no, I think when they put the diff into the USDM evo 8/9s they did that on purpose for noise. at least i don't think it's the case for evo ii's, i really have no idea

 

I have to agree with this, restacking the plates would in theory be legal in any class if I read the rules right. When doing the restacking no parts are changed or altered, same stock plates just the order is changed.

The 2006 US FSM for the Evolution IX lists the plates being arranged in the correct (non factory stacked) order.

From the SCCA 2011 rulebook:

3.8 The entrant has the burden of proving that the vehicle conforms to these Rules by the required Documentation for the category/class, as noted below. The required documentation should be considered as an extension of these Rules.

A. Stock, Street Touring, Street Prepared, and Street Modified – The official manufacturer service documentation for the make, model, and year of the vehicle as entered, if ever available to the consumer from the manufacturer. Additional official manufacturer service documentation for other years and/or models may also be required to cover equipment and/or specifications authorized by update/backdate allowances. Other official manufacturer documentation, such as the owner’s manual, shop manual, parts catalogs, technical bulletins, sales & marketing literature, or Monroney window sticker, may be provided as supporting information. All manufacturer documentation must be for non-competition purposes.

Section 12.4 talks about the part being a factory installed part, which this was, and it was serviced as per the factory service manual which by 3.8 would be used to settle a dispute.

Changing to non factory parts would be illegal, but servicing the factory part and assembling it per the service manual would not be as far as I understand it. Perhaps there is something else that makes it more concrete in the rule book, but everything I've read basically states that since you are doing it per the FSM it is legal.
