ST 35mm Front Overkill for the street?

Hi Everyone,

I'm debating between the ST 35mm front bar and the bmr 32/21 package. My car is basically a street car and I'm looking for better handling. Shocks and 1LE front springs (if I can find them) are in the works, but I'm still stuck on which bar(s) to get. Right now I have the stock 30/19

Thanks,
Dave

Do it. You'll love it. Try to get a 21mm for the rear but you'll really like the 35mm.

I run the ST combo (35/25) on my street car, and with a rod-ended PHB, it's quite nice.

I third that one!! Actually, back in the early '80's I had a brand new 80 WS6 TA and loaded it up with Herb Adams stuff. I had a massive sway bar (I think it was 1 5/16) ) with rod ends for attachments along with a 1" rear bar. Cornered as flat as a steamroller. That's when I learned to appreciate big bars.

YES!!! It's a completely different car with the 35mm on it. You might want to steer away from the rear bar though. A strong bar on the driven wheels will make the car very easy to spin the tires while cornering. The 35 bar is stiff enough that the larger rear bar isn't needed. UNLESS - you're big into drag racing and are throwing down some fast ET's. In that case it will help you even out the downforce between the two rear tires for better 60' times.

As a general autocrossing rule; running a soft bar on the driven wheels and a strong bar on the other two is the best setup. That's why all those FWD 4 bangers lift a hind leg in the corners.

Thanks Sam!

Those we're on my Herb Adams sway bar from the early eighties. The mounting hole on the end of his bar was turned up, instead of the link sticking straight up in the bar it was horizontal. In the picture the top link should be facing to the right and that's the one that attached to the bar. Sooooo, no, not now I don't. I WISH I did. It was a very slick setup. Herb!!!! If you're out there, come on, make some more stuff!!!!!!

Now that I think about it, the bars Herb made were heat treated, they were very rough and sort of scaley unlike the bars you get now a days. Makes me wonder if the new bars would twist and eventually deform. Heat treating makes them resistant to that.

Also, the nice thing about his links is that they allow you to preload the bar or take preload out. Each side could be adjusted individually to take some wedge out or put wedge into the suspension. They really were very slick.

Edited AGAIN.....

I use to have a Rancho bar that used rod ends. It had a collar (for lack of a better term) that slid over the bar and attached to the rod end.

Hmm. A local AutoX racer/engineer makes adjustable sway bar brakets. I wonder if that's what they do.

bruecksteve,

Interesting, I have that exact same,Herb Adams, setup on my 84 Z28 race car. The car stays flat and the responce on turn in is great.

Hotchkis makes rod end links for their C5 Corvete sway bars.

I also noticed that SLP has rod end links for their 4th Generation F-body sway bar kit. But you have to buy their sway bars, and the whole kit is kind of expensive.

As for the ST 35/25 combo, I'm very happy with them.
