Hey all,

I am new to this forum, several customers have let me know about it. I own a shop in the California Bay Area that specializies in rollcages and suspension design. We mainly do BMW and Porsches, but I really like the pro touring cars and am trying to figure out what to build. Hopefully I can help answer some questions when it comes to rollcage and chassis design.

Hey, Tony, welcome to the board! There's another thread in this forum (should be towards the top) about what material to be used for rollcages...maybe you could poke around that thread and give your advice/opinion. I'd be interested to hear what you have to say.

Hey, I have been thinking about a nice BMW 635 with a Turbo LSX, and a 6-speed. That would make a nice pro-touring ride! Too many projects and not enough funds right now, but I am going to build one in 1:24!

Hello there Tony, glad to see you here.

Im True Tourtillott (the guy that keeps bugging you with questions about a '68 Camaro). I expect to have the car ready for you in about 2-4 months.

In this forum you will find a number of threads regarding roll cages, seat installation, harness installation, fire systems and general vehicle safety. I'm sure all of them would benefit from your input.


Guys, if you have a chance go check out Tony's website. Dig the WRX he helped build that in it's first race competed in and finished 3rd at the 25hrs of Thunderhill.

:lol: Welcome to the site.


Since you're a rollcage guy i'd like to pick your brain a bit. What are your thoughts on DOM vs chromo ? A friend of mine is bound and determined to use 4140 chromo for his cage, but I honestly feel it's a bad idea. Mainly due to the inability to anneal/heat treat the entire cage, and that the weld areas will become brittle and more likely to crack.

Am I on crack?

:eek: Ok, I will try and go through one thread a day till I'm down your list!

4130 vs DOM My thoughts...

4130 when properly fitted and welded does not need to be heat treated in a post process, for the thicknesses used in typical rollcages. However a lot of fabricators can not achieve the fit and have the welding skills to get this done. You must make sure that you do not put any more heat than needed into a weld.

Given that, why would you want to use 4130 over DOM for a rollcage? (not a tube chassis) Yes it may be a little lighter since you can use thinner wall and diameter tubing, but how much of a difference is 30lbs going to make in cars that are ~3000lbs. Another reason that we don't normally use 4130 in rollcages is how it stands up to crashes. Often 4130 will shear and crack in multiple impacts. This is not a good thing when you are barrel rolling your car 5 times. DOM will tend to just keep bended more.
