Spec C aluminum roof
�
�
Where do you think I should try to get the JDM Spec C roof? My friend claims it's aluminum. My STi roof was damaged by a branch and I'd rather lighten up while replacing it. I'd be interested in carbon fiber if anyone's ever seen one of those.

It would be hard to get an aluminum spec C unless you really have that much money to waste on a roof. The price will not out weigh the benifits by a long shot. How bad was your roof damaged? A new roof is not a bolt on job unless subaru changed the design but i doubt that.
| Lelandjt | 11-14-2005 05:07 AM |
What? Like the roof panel isn't replacable? I'm just talking about the sheetmetal panel. It got badly dented from this falling branch. I just assumed it was like all the other body panels on the car, replacable. My friend told me that the Spec C, sold in Japan uses an aluminum roof panel.
| Lelandjt | 11-14-2005 05:09 AM |
I haven't seen the car yet cuz I'm out of town for another month. I know I'll have to take it to a body shop but I just was trying to find the silver lining to this.
| austenf740 | 11-14-2005 05:17 AM |
I believe the new model spec C's have aluminum roofs. The roof is replacable but it is not replacable like a bumper or the front fenders. If you are lucky and the roof wasnt damaged very bad.
| Lelandjt | 11-14-2005 05:42 AM |
If I'm lucky I guess they'll just knock out the dents, but if the roof panel needs to be replaced what is your favorite source for JDM body parts?
| austenf740 | 11-14-2005 06:16 AM |
Maybe try gruppe-s or someone who builds rally cars that might have a damaged spec C and be willing to cut the roof off for you. Good luck on your seaching though.

An aluminum roof would need to be packed [i]very[/i] well to ensure it did not get bent or deflect while shipping.

also aluminium and steel dont weld together nicely so most likely like the evo RS and MR models, the aluminium roofs are machine rivited to the steel, not welded. i really dont think this will have a huge effect on the cars handling. take it for what it is, but i watched the mr test where they tested the MR vs the evo(steel roof), and actually ran faster times in the mr after putting a eight pound weight to the top of the roof.

Why not just get a custom Carbon Fiber Roof made up?! If your going to waste money you can fabricate a CF roof which would be uber cool for a few thousands bucks.
| azimiut | 11-14-2005 12:40 PM |
they have carbon fiber roof pieces BTW

You'd have to order the roof vent as well as the spec c roof is most likely precut to fit it.

why have a lighter roof or trunk anyway if it looks the same?

Lighter weight = improved performance, essentially.. better acceleration, better braking, better cornering, all else being equal. Look at the Lotus Elise for an extreme example.

Not trying to hijack, but anyone know a cheap way to get that cf roof shell to the us? I called Bulletproof, they want like 700 for it.
| Der_Dude | 11-16-2005 05:56 PM |
how much will it drop your quater mile and lap times by...maybe shaving off 3 seconds from your lap time, just enough to get 5th instead of 6th place right? You could also drop .001 seconds off your quater mile time (assuming perfect shifting). After all lighter weight = better acceleration, better braking, better cornering, all else being equal.
my point is that in less you are competing with other ppl why do such minor improvements matter at all?

What exactly is involved with replacing the roof panel?
Say, for example, someone has a WRX with a sunroof. But instead, they want to get rid of that sunroof, get back their headroom, and install a Spec C vent?

that carbon fiber roof is wow
| EJS | 11-16-2005 06:38 PM |
i had to get my roof replaced after vandalism. Under the roof rails the roof is welded. Need to cut the welds, replace the panel, then weld it back up, seal it. My bill was over $2500 to get the hood and roof replaced... I looked into the CF roof but at the time i wasnt lookin to spend money on top of what insurance was covering...
| MattDell | 11-16-2005 07:35 PM |
Does replacing the roof reduce the structural rigidity of the car?
| EJS | 11-16-2005 07:41 PM |
nope. i took it to a really good shop. Its exactly how it was before... it was just the roof panel that was damaged, not the actual crossmembers/Bows... So its just the skin paneling... not structural. Some idiot jumped on the roof of my car, as well as the aluminum hood. Like three weeks after i got it. Thank god i didnt see the guy do it, id prob be in jail :)
| damonmlime | 11-16-2005 07:42 PM |
Almost anytime you start cutting on a unibody car you will lose rigidity. Very few people can make a weld stronger than a solid piece of metal. The people who can dont usually work at the local body shop.
| MattDell | 11-16-2005 07:57 PM |
That's about what I figured. Although, what about if a rally shop were to do the work?

The big names, like Vermont Sports Cars, cut out the roof when they install a roll cage. What if you were to contract a place like that to replace the roof skin?

| theicewall | 11-16-2005 08:11 PM |
Most shops wont touch it because it is a roll-over reliability... as anything you do to the roof or damage done to the roof degrades the durability and structural rigidity.
| EJS | 11-16-2005 08:17 PM |
i dont think the roof paneling is a structural part of the car by any means... Its the bracing under it that keeps the car rigid. The panel can be pushed by hand and make it dent... If you need to replace roof crossmembers then thats a diff story...

I don't think that dropping, say, 8 lbs from the roof will reduce lap times by 3 seconds. It might do .001 off of your quarter mile time, though.
I think the point is that many tiny changes will eventually add up to big changes. It's like why people strip their interiors. The rear seat weighs like 5 lbs, but people will still take it out. Bunch of little changes.
Other mods are pretty minor, as well - but 5 hp here, and 5 hp there eventually add up as well.

The roof is just spot welded to the car. If you remove the black strips on the top there, you can see where the welds are.

Remove front and rear glass
remove roof rails
remove interior trim and headliner
cover all interior because the sparks are going to fly
Use a spot weld cutting tool, cut the approx 40 spot welds in the very tough high strength steel roof
grind the remaining sheet steel flat and remove all paint and sealer
reinstall new roof panel by either welding (a good chance you'll warp your new roof from heat) or with metal glue (my vote for both strength and minimal damage)
Repaint the roof (inside and out)
re-install interior trim/headliner/glass.
Cutting the welds is a pretty tedious and risky job. I've done it before, and I would rather gargle with paint stipper than do it again...

Best motoring did a test with the evo MR or RS whatever has the aluminum roof and they said it is a noticeable difference. the fact that the weight was taken off from the top of the car ment it rolled a little bit less. since the weight taken off was from a high center of gravety or something to that respect

watch it again they run a faster time with the weight difference of the steel hood on the mr's roof. it would still be cool to have a aluminium roof, or that luansport cf roof/

The launsport roof is a cover for the factory roof not a replacement. I've spoke with Steve at Aerosim Research about making a dry carbon piece for my GC and he quoted me a price of around 1200 dollars for a 5 to 6lb roof. Vermont Sports Car told me that the factory piece is about 25lb and that it is held in with 8 plastic clips and epoxy.
| fragment | 11-21-2005 07:50 PM |
[QUOTE=Wayne_Coots]it is held in with 8 plastic clips and epoxy.[/QUOTE]
I think he was talking about how the rear glass is held in. The roof is spot welded every 4 or 5 inches down the entire length of the roof on both sides.

options:
1)2" chop (like an old hot rod, or the cusco gt car)
2)pound an aluminum roof by hand
3)be a dikfor and buy something off the shelf

Are you sure about the spot welds on a GC chassis? The GD is but I don't think the GC is, And no windshield is held in by clips or epoxy. They use rubber blocks to get the correct hight and they are sealed in using urathane.

'cause some monkey with a plasma cutter thought he knew how to build a race car. He cut out the entire centre of the rear shelf; including the centre seat belt mount and I had to replace the shelf with a new Subaru part.

has anyone ever seen Carbon fiber vinyl that comes in rolls wide enough for an entire roof. To get the CF look at tenth of the price. If so let me know
| theicewall | 01-09-2006 04:47 PM |
I think the entire point was to have a roof that is lighter to reduce the height of the center of mass and thus lower the center of gravity. Im pretty sure everyone who thought this was cool intended on painting their roof. The STi and EVO come painted.
| WikdRX | 01-09-2006 05:33 PM |
WOW i need that CF roof. Too bad i cant read that language on the site to see how much it is. I guess if i have to ask its too much
