Thats cool, ya gotta start somewhere. I've seen some of his work in person, mostly in pics. He has a crazy mind and a lot of attention to detail. I'd love to get a chance to be in a shop with people like that.
Keep on draggin

I definitively want to see what the 2G model looks like

Well I tried to post in the fourm but it would not let me I guess because I am still a newbee. I just wanted to caution 1fastlaser about the use of mild steel as a base platform for a k member. I have a degree in engineering and am a registered engineer in SC so I am a newbee to DSM's but not to engineering. Mild steel has a value of 36ksi and on 1.5" tubeing with .200" wall that equates into a radial section of 1.125" and an elasticity of 3.36 that is going to = way too much deflection. I would not waste my time on a mild steel version of this just because of the safety factor and go with a 52ksi chromolly version with proper bracing to handle lateral loading and deflection. The best of luck in the fabrication and most of all do lots of testing. Also the truck frame is unreal I need one of those.

I understand the numbers, but real life data is also important. I have about 300 miles on it, 5 passes and typical street driving. Acouple massive bumped on the highway, speed bumps, and hard turning. Everything is still in check.

Well send it to me ( i will pay shipping) and i can try it out for you, I have the don polk subframe and We could compare the two.

This is my best friend punisching his gsx
http://www.garaget.org/video/82wphxzoaqoq

We would be able to provide a different betwen the two.

That must have been fun as hell! Awesome!

bmoha2 · 10-25-2007, 04:29 PM

I can't find any info or pics about the don polk subframe. I would like to see what it looks like.

donk · 10-27-2007, 06:28 AM

This is the one

1fastlaser · 11-17-2007, 05:08 PM

2000 miles on it and still good to go. Besides the point i have no traction what so ever on 29psi. Acouple of real hard launches. We are incorporating driveshaft loops also now. I wanna get to the track and get some slips but i need atleast drag radials before i go.

laserspeeddemon · 11-20-2007, 03:13 PM

Are they being sold? I just put a huge crack in mine. If I have to replace it, I may as well upgrade right?

1fastlaser · 11-21-2007, 06:07 PM

yes there being sold. We are also incorporating the driveshaft loop on request

KGB Pilot125 · 11-21-2007, 06:40 PM

How much?

laserspeeddemon · 11-21-2007, 08:01 PM

Please give me a link or PM me a quote. Also I need to discuss things like warranty and durability.

1fastlaser · 11-22-2007, 12:09 PM

For mild steel 550, chromolly 850. driveshaft loop is 50 extra on each as some people might not see a need for it

Lifetime warrentee, its really durable. I drive my car often and have had no issues, more then a dozen sideways hard launchs

laserspeeddemon · 11-22-2007, 08:19 PM

What about the stress of Rally.

We have yet to make one for a 2g, we dont have anybody with one. We acually have a buddy of mines car down there (alex from dogboxracing.com) I got him hooked up, and he got some custom stuff done for his new evo race car. 03 cobra rear mounted in with a custom tubular rear mount all tied into the cage and the paracute mount. He might be making a k member for that also. Im still running it, 0 issues. I have about 4k on it now

Yeah its weird. My daily is a wicked white evo mr and seeing it torn apart like that almost makes me sick. They really are tin cans. The rear mounted in nice th
