I noticed in the One Lap artical you guys listed Addco as a sponsor. Are their bars any better for autocross? ASP Z06, stock springs, Koni singles, poly bushings, 315/18 710's on all corners. If so what size. I spent 6 months trying to make T1's work after Thomason told me I'd never do it. He was right! Thanks for the help

I know the east coast guys (Strano, Salerno etc.) swear by the Addco 32mm bar. They also have a 35mm available.

Bob,
Sorry I didn't get to meet you in Topeka, I believe you were there weren't you???? Things were a little crazy out there as you know.
Yes we used Addco bars on the One Lap ride, additionally I use them on my vehicle . Both vehicles share the same sway bar set-up. The front is a 35mm and the rear is a 25mm. This is more than the supposed SS set-up both front and rear (Strano's gang likes the 32mm front and obviously SS mandates a stock rear ). Sway bar choice can be dictated by many things, driver preference, alignment settings, shock type/valving, tire size etc,etc.
Since I have returned and have been testing primarily on asphalt I believe sway bar choices are going to change , but thats based on in-town asphalt, not the supposed "high-grip" stuff that they are pouring in Topeka. ( 1000 x 1000 is too small for 2 national courses BTW ) We have test-n-tune scheduled at our asphalt lot, I will learn more until it gets too cold.
Thomason is very right about the T1 bars, defineatley will never work on a Solo2 car. I used to run only the rear with a stock 30mm in front and that was not too bad especially on tight courses. I dont even like T1 bars on my car on a roadcourse. I prefer to use "alot" of spring rate vs alot of roll coupling-----seems to make my ABS happier.

What size are the T1 bars?

My notes have the T1 bars as 38.4 mm front and 27.5 mm rear, with a 1/4" wall thickness. Anyone have anything different?

Danny, thanks again for the help. I'm going to try them. I bailed on Topeka this year at the last minute. With the events in the south it just became to expensive a drive for a Solo2! There's next year. I was so stubburn with the T1's, I was sure I could make them work. I loved them high speed on the track. I loved them anytime the wheel was turned less than 90 degrees and I learned alot. I learned how to change alignment in grid, learned how to ruin $460 dollars worth of front tires in a day. I just learned to do alot of neat stuff to ruin a perfectly good race car chasing those blue bars. But... I've got some neat pictures of a Z06 autocrossing with air under the inside tires! :lol:

I have a 32mm addco front bar - used once - in the closet if you need one for a good price ;)

If weight is an issue, also consider hotchkiss, as they are lighter (tubular). They are 32mm tubular fronts.

Just out of curiosity, how much does the Addco 32mm bar weigh versus the Hotchkis 32mm bar? Is the roll stiffness equivalent on both bars? Thanks.

I think the current Addco 32mm is tubular, not solid. Also, the application is with the stock Z06 rear bar. I haven't tried it, just reporting what I've heard from those that have!
