I know they make kits for several bmw models just haven't found one for the ti, not sure if a kit is even made. So if anyone has some suggestions or knows a kit please link it, thanks!!! | | | 01-18-2014, 06:54 AM | #2 | Junior Member Join Date: Jan 2014 Location: Edmonton, Canada Posts: 6 | Unless you are hard core racer and already shaved pounds in all other obvious places (including weight of the driver) there is no reason to do it, unless you have too much money.

Interesting note I found http://www.318ti.org/forum/showpost....7&postcount=16 Quote: Lexan is cool, but not that much lighter than the stock glass. A local NASA driver went full lexan on his GTS4 M3...he saved 6 lbs on the windscreen, and about 20 lbs on the rest. He said it was a nightmare to swap, too. | __________________ ...steven BMW CCA #146825 1996 BMW 328ti • 2003 MINI Cooper S • 2016 M235i www.bmwcca.org | | | 01-18-2014, 05:20 PM | #4 | Member Join Date: May 2013 Location: Scottsdale, AZ Posts: 51 | Both for weight and safety.

There are a number of chemicals that will make polycarbonate crack if it is under stress, including: air conditioning refrigerant, anti-freeze, brake fluid and gasoline. If you want a spectacular demonstration of what can happen, find a CD or DVD you don't care about and wet a rag or towel with acetone. Make the CD/DVD bulge up by squeezing it at the edges, and then swipe the rag across the bulge.

It's honestly not worth it. Get a carbon fiber hatch or something if you've got money burning a hole in your pocket. http://dtmfiberwerkz.com/access/styl...frp-p-349.html __________________ -'98 318ti -'87 VW Scirocco, 2.0 Motronic swap -'95 VW Cabrio | | | 01-20-2014, 05:58 AM | #9 | Member Join Date: May 2013 Location: Scottsdale, AZ Posts: 51 | Thanks for the link that is exactly what I am looking for. I understand all of the pros and cons. I did my homework before asking my question. I think for a dedicated track car the lexan kit is the best route. But I won't know for sure until I try it.
