The lower arms may not be altered, except as permitted
under 15.8.C, or relocated.
Methods of attachment and attachment points are
unrestricted, but may serve no other purpose (e.g. chassis
stiffening). This does not authorize removal of a welded-on
part of a subframe to accommodate the installation.

Clarification please? If stock mounting points are used, but the lower control arms are replaced with aftermarket, is this legal in street prep.


also switching from rear drum brakes to rear disc brakes. That is not mentioned in the rules for brakes at all.

As for the Lower Control arms they are a no go you can not replace them in Street prep you can change the bushings and thats really about it.

The Brakes Depends. Accordingly you can do update back date on it as long as they bolt up using factory componets from a later or ealier model year of that vehicle

15.1
C. Equipment and/or specifications may be exchanged between
different years and models of a vehicle if (a) the item is standard
on the year/model from which it was taken, and (b) the years/
models are listed on the same line of Appendix A (Street Prepared
Classes). The updated/backdated part or the part to which
it is to be attached may not be altered, modified, machined or
otherwise changed to facilitate the updating/backdating allowance.
Standard factory installation methods, locations, and configurations
are allowed.

The updating and/or backdating of engines,
transmissions or transaxles must be done as a unit; component
parts of these units may not be interchanged. Cars not
listed in the Street Prepared sections of Appendix A may not be
updated/backdated until approved by the SEB and published in the


Hope that helps you out

well from what i gather with that todd is that i can switch to a rear disc as long as it is from the same line on appendix A. So lets say i go to the junkyard pick up the rear disc swap and LCAs from like a 99 SI and it would conform to the appendix on doing the swap? Using stock parts, but just replacing parts with oem to accomodate the rear conversion.

Rules can be so confusing. I really want rear disc lol

From what I gathered by what Todd posted yes you can swap out the rear disc's from an Si to a non-Si. Clarify Todd if I'm incorrect.

Eli that falls under the update backdate rule with SCCA. What are you planning on doing to the car? I can get you a pretty good idea of what class your going to be running in.

well this year i am going to run DSP next year is going to be a different story though. i am going to be tearing the car apart and redoing everything on it. Built motor turbo full suspension. everything that i want to do to it.

Blackeg- you should be able to run your stock LCA's and put rear disks on the car...

well i am going to be switching it up this next winter. I am going to be doing the type r front and rear brakes and 5 lug swap. so this year i am going to be running just the stock brakes and maybe change out the stock bushings for ES bushings.

why do you want to go to all of the work of changing your LC''s??? a decent of brake pads will be more than a noticable difference, especially in auto-x. Plus, then you wont change your class which will mean more comparable competition and a better chance of being competitive...
