Drag Racing Tech - Rear Speedglass- Myth or Not?

I've heard some of the guys around my area claim that installing speedglass in the rear of the car will throw the balance of the car all off and you can't get the car to work again without adding balasts. They also say its structural and "will cause the car to flex to much"

Myth or not?

I think they are retarded.... but I may be the 1 who is wrong.

sorry if this issue has been brought up before but I have looked far and wide and havent found anything on it

Wow.......lol. Sounds like they don't know what they're talking about.

yeah kind of what im thinking. I could call em other things too... but yanno

If stock glass is what people are relying on to structure their racecars then I'd be afraid to line up next to them. :jest:
Keeping the front end down is the issue once the power does up and u start getting it to the ground efficiently. Weight ballasts?? :jest: I dont think so, not in these cars.

yeah these folks are claiming that the cars just will no longer work once you install speed glass in the rear.

I call BS I was just wanting to see opinions of people that ARE going fast

Rear speed glass here ... no ballast here 1.24 60s with zero issues... sounds like a few people don't have a clue what there talking about

exactly what im thinking! lol 1.24s sound its working pretty darn good to me!

SSPerformance, have you got the glass hatch aswell?? Funny though I heard the same myth and posted about this a year or so ago, and im in Australia! I also heard that the front winscreen was a major structual tie! All my glass is gone now though with a vfn hatch also! Structual my ass.

I have the factory glass (by rule) and it in no way aids in the rigidity of my chassis. The weight is in a good spot, but I don't see how removing the weight in that area would hurt the car all that much.

I will say that I replaced my windshield with a Chinese glass replacement. It saved me 4.5 lbs in a very good area. Now the funny thing is that 30 minutes after I make a run, I want to make another run.

I have a Crabon fiber hatch

That Crabon must be a new kind of material. :jest:

That Carbon must be a new kind of material. :jest:

I mean Carbon :buttkick:

SSPerformance, how did you fit your speed glass?? Have you got any pics??

We stock Speedglass and have done several of the installs but never heard of this rumor before. I would have to agree with the below statement.

Perceys direct fit

just thought I would throw in here, speedglass is no longer sold thru Percy's due to some contractual mis-steps by them. The manufacturer is Optic Armor Performance Windows and the windows are now marketed as Optic Armor. Percy's was simply a distributor. Just wanted to clear that up since Ive been seeing a lot of posts where folks have been trying to contact Percy's with no luck. These are the guys that actually produce and sell it. www.opticarmorwindows.com

Wow, talk about some miss info. but it happens and let them think they dont need it. Give you an edge, Period.

I moved JL front and rear at the same time and it was so freakin light, it was disgusting.
