STL rule questions:

Is the weight min., with or without driver?

If removing the sunroof can the OEM (sunroof) roof skin be removed, and a OEM (non-sunroof) roof skin be installed in it's place?

Cars that have a hatch, are cf hatches legal?

Thanks

With.

Sunroofs are not specifically mentioned in the STCS. However, given that engine swaps are legal, if any version of your chassis came without a sunroof then it's legal. If no version of your chassis came without sunroof, then I'd suggest it's within the spirit of the rules to allow that; send in a request for clarification to the CRB.

STL rules state, "...may replace the hood and trunk/deck lid with nonmetallic composite parts." I suggest hatches are well within the spirit of that rule, but I can see the confusion. Hell, I am planning on doing a CF hatch on my Integra and hadn't really given it a second thought! How about you submit a request for clarification immediately (the next STAC meeting is tomorrow night) and we get that clarified...?

Thanks Greg! Didn't get a chance to send in a request for clarification but will do before the next meeting. When is the next meeting btw? Have a few things I want to submit before the next meeting.

I am sure to have more noob questions also.

Don't bother, already in process. Watch for the next Fastrack, mid-month...

STAC meetings are first Monday of each month. - GA
 
Ok thanks.

Another question, is gear size free (as in aftermarket) or do they have to be OE size?

If they have to be OE can gear size be mixed and matched from different model transmissions?
 
STL 9.1.4.3.C.3:
Either the OEM transmission or an alternate transmission must
be used; the alternate transmission must be from the same
manufacturer as the vehicle (e.g., an Acura transmission may be
installed in a Honda car). Alternate transmissions must be used in
their entirety. Retrofitting OEM complete gear sets in an alternate
transmission case is permitted.
​
I suggest the rule's intent is to allow swapping of OEM parts/transmissions/transaxles. I don't think it allows you to change gear ratios to something not OEM. I, for example, am using the Type R transaxle and gearset in my GS-R Integra.
 
As a clarification to that though, you can't take a 5th gear from an Accord tranny and stick it into a Civic tranny or whatever (only cause I don't know the Honda engine codes well) to mix & match ratios.

i.e. the Nissan KA24 engine was used in a bunch of Nissans. the 240SX has a 0.83:1 overdrive. The Hardbody truck used the same engine but the overdrive is 0.90:1

In Prod and STU, they tend to take the 0.90 gear from the Hardbody and install it in their 240SX transmission. Can't do that in STL since you would have to swap the entire guts.

That said, if the rest of the ratios are the same for that tranny (or more desirable), you could swap the entire guts from the hardbody tranny into the 240SX tranny and be okay.

HTH.
 
Ok I see, you can't piece together the perfect gears from different honda transmissions.

Another question. Is this legal to do for nascar bars, where the door is notched a little.

I don't know what you mean by "notched", but Super Touring follows GCR 9.4, which allows gutting of the door for NASCAR-type bars. - GA
 
Sorry should have been more clear. Talking about the B-pillar. If you look it has a notch for the top part of the nascar door bar. Is this legal.

Thanks.
 
A fair question. To the "letter" of the rules, it's debatable; some folks take the position that any "reasonable" mod is allowed for rollcages. To the "spirit" of the Super Touring rules - given no limit to attach points and seam welding on the chassis - I'd say it's OK.

My recommendation is to talk to the local inspector that will be issuing the logbook and get their opinion. - GA
 
Thanks guys. Yeah I think I could just weld in a patch (that has been massaged with a hammer) paint match it and be good.
 
Ok more cage questions. Not an ideal looking cage to me but would this be legal in STL.

Specifically looking at the roof hoop, A pillar down bars, and the extra bar coming of the main hoop to the floor.

STL does not have a limit to the number of attachment points for the rollcage (Improved Touring does) so as long as the cage meets GCR specs you're good. Review the GCR for the front hoop allowance (it's there, I just don't know it by heart.) - GA


On edit: on first glance it will definitely need a diagonal in the main hoop plane and more door bars, but I think the general idea is OK -- read the GCR to make sure.
 
Thanks just re-read it and the front should be legal, yeah definetely needs door bars and and crossbar in the main hoop.

Thanks!
 
If I understand the rules correctly, it's not unless there's a second metal cover over the filler area to be added later.
