So, I have decided to finally put a full cage in the del sol. I have realized I really want to start competing in this car, so here are the first steps towards running in Honda Challenge H1. So far I have just stripped out the interior. Cage fab work will begin July 1st. I'll post more pictures when that part is complete. Here is how she looks right now. Originally she weighed 2422lbs, she is now down to 2160lbs. I would like to find more weight to remove, I'm sure I can.







New NRG Suede wheel with NRG quick release and short hub.



If anyone has any other weight removing ideas, let me know. :P

love that wheel!!

micah

cf trunk/hood/roof are all possible. the plexiglass roof like i used to have weighs even less then the cf ones you can buy, but they are hard to find.

you gutted the trunk too? not much in there, but maybe a few pounds worth.

Smaller fuel cell? Carbon fiber dash?

I don't know what that seat and rails weigh, but maybe a fixed seat thats lighter.

B16

The dash is gutted and doesn't weigh much. I think once I remove the latches to the roof the skin alone will be very light. Trunk and hood, I think I might do. The trunk will have to have holes cut in it though to allow the rear bars of the cage to mount in the trunk. And yes, the trunk is completely bare. How much do you guys think the front and rear bumper supports are? I would like to lose more weight on the front to help balance since majority of the weight has been removed from mid to rearward of the car. Also a fixed bucket is already going in, either Cobra Suzuka GT or Sparco Evo 2, we need to mount it quite low in order for my helmet not to hit the halo of the cage.

I'll have to check that out. My buddy runs an Odessy mini batter and has had it die 2 times on him. I guess since this is track only car it really doesn't matter, just needs to be started.

I heard the NRG wheels are madein Taiwan and are crap. It looks a little funny. Looks like the padding is huge.

Wheel has a nice design. I just ordered my short hub adapter. Deciding on what wheel to buy.

You lost almost 300 lbs, how much of the interior is going back in? How much will a full cage weigh?

They may be made in taiwan, but i'm happy with it. It is very thick, which is actually nice.

No more interior is going back in, only adding cage, replacing drivers seat/seat belt with bucket and 6pt harness. I'll be putting the stock del sol seat back in the passenger side with a 4pt harness for instructing with the car, to take passengers with me. When not instructing though, no passenger seat will be there.

not at all. 5-7 lbs tops.

pissedoffsol

are you sure thats legal?

around here the driver and passenger are required to have the same style seat and restraints.

B16

for HPDE? why? I have never seen nor heard of such a thing. Almost every car that has an aftermarket drivers seat has a different passenger seat.

exactly, the passenger seat will be empty if I'm racing. Infact, there even wont be a seat or harness when the car is competing. :P This isnt' rally B.

You might look into Corbeau Clubmans. If you have a 33" or smaller waist, they will hold you firmly, are safe, good seats, and are pretty cheap. I think I paid $600 for mine with harnesses. They are rediculously low weight too, something like 11-13lbs a seat.

(at the time I purchased them I had a 34 inch waist and they fit me very snugly. 33" would probably be perfect)

Dont forget the wheels! Throw some Motegi trak lites on there!

Massive weight can be saved in the wheel department, and its unsprung weight too, triple bonus. Forged aluminum lugs if you want to get all crazy about it. Replace all glass with lexan or completely remove what you can get by with removing. Pull the supports out of the hood and trunk so they are just skins, remove all latching hardware, cables, hinges, etc and replace with those body locks or aluminum pins from autozone. That'll get you CF hood and trunk weight for damn near free, freeing up more fundage for seats, wheels, tires, etc.

I assume you've pulled up all the sound deadening material from the floor of the car? Thats something like 20+ pounds right there.

Getting picky: Pick up a set of el cheapo aftermarket side mirrors. Stock units weigh around 2 lbs each, those cheap ebay ones weight a little over a pound for the pair. "spoon" mirrors ftw! lol

P.S. Leave your bumper supports alone, they weigh less than 10 lbs each and you'll love them if you smack a wall or bump another car fairly hard. The safety they provide far outweighs the weight penalty of having them, and may save your car from being totalled in a minor collision.

Good god, I've edited like 10 times... :P

One more thought: I know you got headers already so you saved the weight there. You might see if its legal to remove the rest of your exhaust and have a pipe dump out right next to the front wheel. Lots of weight savings there. Aftermarket intake manifolds are usually alot lighter than stockers too, but thats $400 for a few pounds... kinda going too far there.

Ya, I have trouble finding good seats since I have a 38" waist and weigh 210lbs. Being fat sucks. The Cobra seat is around $700 and is very light. My buddy has one and says it is very comfortable. I'm 90% set on getting that seat.
Wheels, I currenly use Rota 15x7 slipstreams for the track. They already weigh around 11lbs each. And ya, I do have aluminum lugs for them, lol. All windows will be completely removed except for the windsheild, which I have to leave as glass. I already have the rear glass completely gone. I have left the side glass since I have to drive the car to and from the track. I'm keeping my eyes open for an old truck so I can buy a trailer for this thing.
Good idea on removing the support and latchings. How do I go about removing the support? The trunk is already going to have to lose the hinges and latching because of the rear bars that will be going through it. Yes all sound deadening is now gone. I think I got about 10lbs worth from the sol, since there were only 2 slabs of it.
About the exhaust, it depends where I run at. Sears point and Laguna seca have some strict sound rules, and you'll get black flagged if you're over 95db. Thunderhill is even starting to adapt this sound level. I think the only tracks left that don't have it are Reno and Buttonwillow. I suppose I could look at a different exhaust though, the one I have is from the muffler guy down the street, I have no idea how much heaver it is than some aftermarket piece.

Not steet legal, but a few more things I thought about. Might want to run these through your racing organization, make sure they are legal.

remove the inner door frames, just cut right where the glue is, remove the inner handles and just hang a grab wire out to open and shut the driver door, remove window mechanisms and handles, remove all of the hardware from the passenger door and weld it shut. Dont pull the impact bars out of the doors unless your cage has side impact bars!
-30ish lbs

Windshiled wipers and motors, cowl cover and hardware, dash vents, the rear rubber section of the e-brake (keep the handle), the rubber boot from the shifter, buy a 4" hole saw and go nutz on the back bumper and dash pad.. -10ish lbs.

I wouldnt mess with changing the dash pad over to aluminum, stripped honda pads hardly weigh anything anyway, and are more comfortable when your knees smash into them.

Check the engine bay too.. Washer fluid resivoir+motor+tubing+hardware

Also, if you are going with an aftermarket intake, be sure to get the factory silencer from under your front bumper. Along with all of the rubber splash guards in the wheel wells and underneath.

p.s. $700 for one seat is a little on the nutz side. you can get really nice seats for half of that.

All the internal ribbing under the trunk and in the doors, under the hood, ect. That stuff adds alot of weight. not everything can be solved with carbon fiber, although i wish it could be.

Start hacking away at the floorpan...You could probably lose some weight by removing the trunk flooring and replacing it with lexan or something. Just don't wreck. Lmfao. I've heard of a CRX driver doing that...Also, you can always just take a circle cutter and slice 1" holes out of your stock metal doors.
