Are 5 lug and suspension arm swaps legal?

Are 5 lug and suspension arm swaps legal as long as they are from the same manufacturer?

Opens up better brake options and wheels for civics...

Also are steering rack swaps within same manufacture legal?

You need to be more specific if you're looking for a reasonable opinion.

IMO, you can swap parts freely within a model of car.

I am talking specifically about 92-95 civic with rear drums.

The 5 lug conversion is done by using type R front knuckle/hubs and rear type R trailing arms and hubs.

I think the above is a no go now that I think about it, since the type R is not allowed in the class.

The Si model came with rear disks so I will just swap that rear disk in.

The steering rack swap is the 94-01 integra (DC) steering rack which bolts right into the 92-95 civic (EG). The EG and DC are the same car. Still not sure I am going to do the steering rack swap as the EG rack is already manual vs the DC being power. Lot of track DC guys actually put the EG rack in.

The Type R chassis is allowed in STL but it's not a Civic. IMO, putting Integra parts on a Civic is non-compliant to the regs.

We had a situation appear in Fastrack within the last month or two, where the CRB had a discussion regarding swapping parts between different versions of Miatae (NA vs NB). The CRB published in Fastrack that the NA and NB versions of the Miata are considered separate chassis, thus you cannot swap parts between them.

That statement has been subsequently retracted so this situation has not been clarified. However, this Miata example should give you a general idea of how the CRB would respond if they were asked for specific clarification.

In my opinion, and it's just one club member's opinion and is no way an official one, it's safe to swap parts within the same manufacturer chassis codes (EG, DC, EF, etc). Outside of that is up to your personal interpretation -- and risk.

Greg, wasn't that "clarification" since retracted about swaps between the 99-00 NB and 01-05 NB Miatas which the rest of the world considers to be the same cars with different engines and some minor updates to trim and lights?

I agree with tGA, though, a part is either stock (or stock equivalent) or not stock, and only stock is allowed unless permitted to be changed (I.e. brakes).

BUT given the lack of replacement hub availability on so many cars it might be nice to have some sort of allowance for better than stock or at least similar to stock matches, as long as you keep the stock knuckle and bearing OD, who really cares?

Yep, I think you're right. Which is why it was that much more confusing...

...might be nice to have some sort of allowance for better than stock or at least similar to stock matches, as long as you keep the stock knuckle and bearing OD, who really cares?

I suggest that idea is within the general philosophy of the class, as long as modifications to the car are not required to make it fit. If you (or anyone else) can come up with some non-intortuable verbiage, submit it for consideration. Make it snappy if you're looking for implementation for 2014...

I'll quote you a couple pieces from the above:
