Do you actually need working doors? If not, I may be working on something you'd be interested in.

Definitely. Keep me posted. What I was thinking was having DHP use a stock door/window to make a mold negative of just the outside profile, then just lay up a couple sheets of carbon w/ a honeycomb core.

 

Nice work! If I ever decide to move from SM to prepared, I might have to do something similar.

 

Also keep in mind the windsheild glass is a bonded structual componant. New car rigidity includes the glass. That is why new race cars do not need safety tabs to hold the windsheilds in place like cars from the 70's.

 

vacuum formed ABS plastic evo doors perhaps?

 

Going to be doing rear quarter panel/door combo piece. I'd been thinking about doing for a few years, and now that Rally America has approved them for use on stage rally cars (in addition to GRC cars), I'm jumping on it.

One of the Evo's from X-games had them...but I want to be able to stick wide tires on the car, so I'm doing a widebody version of that. From what I've heard, I should be able to have each panel weigh under 10 lbs. I'll be posting up progress on them in my 2012 thread: https://www.evolutionm.net/forums/mo...om-2012-a.html

great idea!
Good job too.

 

Since Dave wasn't real sure on these #'s - anyone wanna back him up? Particularly the front windshield, as I'm trying to decide if it's worth it.

Also, if anyone is interested in making pre-trimmed inserts for the doors to sell - it definitely looks like there's some takers (me included).

Also keep in mind that some sanctioning bodies require the lexan to be a certain thickness, so your weight savings can vary a bit based on that.

I made the windows for the EvoD pikes peak car and it was very simple, I would highly reccommend trying this yourself, it was much easier than I expected.

 

Bump from the dead, a little.

But, Jarrod, where did you get the piece of lexan?

 

Www.mcmaster.com

That's where I get most of my raw materials and fasteners.

 

Awesome, thanks!

I will be doing this over the winter, for sure.

 

Which polycarbonate did you end up using?

Mcmaster has several different types. I've got my eye on the UV and abrasion resistant material.

Those numbers earlier must be both doors combined. Here is what I weight for each window this morning.

Front Window - 6lb 4oz
Rear Window - 5lb 5oz
Rear 1/4 Window - 1lb 4oz (with seal)

25lb 10 oz total for the stock glass and lexan will cut it in half saving about 13 pounds.

 

I used the clear non-scratch resistant 1/8" stuff from McMaster. If I was doing the windshield or rear window I would use the scratch resistant stuff for sure!

BTW, I have an extra set of front-door lexan windows for sale if anyone wants them. Brand new with protective wrap still on them.
