Not sure but the head lights might not have a relay, so to much current could be going thru the switch. Adding a relay will greatly reduce the current load on the switch.
Most X 1/9 s didn't have sway bars, it is so low, they are not really needed. There are kits to add sway bars.
Mine I removed the large bumpers and all the bumper trim. I made bumpers out of some light steel tubing, I think the end result is lighter.
I think you are right on all counts. I'm not aware of any x1/9s that came with factory sway bars or headlight relays.
the headlight current goes through not one but two dash switches! A couple of relays would be a good upgrade which I will see if I can easily pull off. Should have all the connections I need right at the fuse box, so maybe not too hard.
for sways, this car doesn't have any and I think the prevailing rules of scca street prepared may have been part of the reason. Previously the lack of sway was made up for with spring rate.
finally, the bumpers are here largely due to scca rules as well. They are heavy (even though they are aluminum), but rules say or used to say that stock bodywork needed to be present. I'm keeping them now not so much because of the rules, but because this is how the car ran, so it's a bit of history, I guess.

I've dusted off a few brain cells with Fiat suspension info in them. Jim Susko ran sway bars on his car, the front was a huge Speedway engineering type hollow stock car unit, 1.125 dia IIRC, but it needed really long arms because it was mounted up in front by the tension rod mounts. The rear had a 5/8" solid bar, arms were about 8-10". I ended up with a lot of his cast offs on my IT car. I forget what spring rates. My IT car had stock springs that were cut and even had chunks of other stock springs used as spacers held in the coils with hose clamps in the front. I also had stock struts with different oils front and back. I was in college and broke but man that car handled, lol.
Steve Hoelsher(sp?), I remember he chuckled at Jim's elaborate calculations and modeling and finally told him he just had something like 1000lb springs all the way around. He didn't have sway bars.
I don't know what Chuck Sample was running but he had Susko help him set up this little beast of a Prepared car that looked more like a road racing car with no windshield. The coolest thing it had was power steering with a steering doubler. Lock to lock was 1 turn.
Oh, on the bumpers. MIght not be a good idea for the street but if you drill the bumper shocks the whole thing will only stick out a little more than the trim.

Yeah, Red was definitely in the Steve "camp" of autox suspension design. I believe the fronts were 550lb/in and the rears 650. While that does make for nice flat cornering, it's a bit rough on the bumps, and at anything other than a large perfect concrete expanse it is too much.
for the challenge this year, I'll be dialing down the spring rates but I don't think I'll have time to add sways on the cheap.
one thing I do have is single adjustable konis, which I think are all in working condition still. What is your opinion on turning up the rebound so the car jacks down onto the bump stops?
im getting ready to install the suspension and I think I was going to start the rebound about middle of the range, but I could be convinced to go one way or the other.
Maschinenbau and dherr, thank you and yes, I am excited for the trip. A little nervous if I'm being honest but either way it should be fun!

I'm nervous for my Challenge car road trip too

Remember I did this to spectate October '22 in the middle of 3400 miles. robbie sold me the electrics he needs now. Relays everywhere including the wipers. Italian switches are less conductive than Lucas for sure.
