Drag Touring enhancements....

[Nine Ball]

Sure, its a "Pro-Touring" car, but with a simple wheel and tire swap, and the addition of a new 6-point rollbar, it sure does look different. I had to reposition the rear shocks upwards a bit, and slightly grind some casting corners off of my fancy front brake calipers, but everything fits now.

28x10x15 Hoosier slicks
15x10 (5.5 backspace) Weld Pro-Stars in the rear
15x3.5 Weld Pro-Stars in the front

These are definitely the biggest tires you can fit under those stock quarters. I even had to roll the fender lips to make them fit!

If the weather clears, and I get some time, I might hit the track tomorrow :3gears:

Lets see some ten second slips!

[Steve Chryssos]

Tony,
Looks great. The suspension is still set up for handling? No changes (such as light front springs)

[Nine Ball]

same suspension. I just loosen up the QA1 shocks alot up front, and those Cal-Trac bars on the rear work even with the car lowered.

If I can cut some 1.5 60' times, hopefully I can get a 10 second slip.

What size brakes are you running tony?

[Nine Ball]

13s up front, I believe the rears are 12s. The front rotors stay about an inch behind those skinny wheels, thats how come they fit. I had to grind the outer corners of the brake calipers down smooth though. I took my time and did those slowly and kept the sanded areas smooth, and repainted the sanded area red again.

Hey Tony, just checking if you made it out. Love to see what times you will pull...what no wheelie bar?!?! don't break anything!

[JamesJ]

No way he made it out, the weather here stinks!! Rain and Rain and more Rain

[Nine Ball]

Its been raining about a week straight here. Today is probably the worst so far. I'm fairly certain the tracks will be rained out tonight.

This sucks! Maybe next weekend, unless a weather miracle happens.

my car is too slow for wheelie bars. What do you think this is, Pro-Street?

[Streetking]

Looks great Tony! The weather does suck, I have been trying to get to the track for 2 weeks!!

Those wheels are awesome! I have a 69 with standard wheel tubs and rolled fender lips. Do you have much room around the wheel well? How close are they to the shocks? I also have some cal tracs. I was thinking of getting some huge 15" tires until I can afford some 17" I pretty much want to track whore my car. The cage will be in soon.

[Nine Ball]

with the proper offset wheels, I have about 3/8" between the sidewall and the stock inner wheel well. Now that I rolled the fender lips I have about 1/2" there between the sidewall and lip.

The tires clear the QA1 shocks by a large margin since the shock reservoir is located on the bottom side of the shock instead of the top.

[Steve Chryssos]

I think the right magazine would kill to run a comparison tech piece on drag racing a pro-touring car. Inquiring minds wanna know:

-How did the wheels fit over big brakes?
Conversely, you can show how brake size may need to be limited if multiple wheels and tires are intended.

-Can the suspension be tuned quickly for improved E.T.?
Coil-over adjustment, sway bar disconnect, etc.

-How does the quarter mile performance compare?
Do a direct comparison: Same day, same track, different wheels/tires/tuning.

Please take lotsa pictures and submit the edit. You will help a lot of people.

[Nine Ball]

Good idea Steve. I'll document everything and take some photos for my website too.

Any pro-touring cars out there with a wheels up launch photo yet? Maybe I can start that trend here. haha

[JonB69FB]

I haven't run skinnies on the front of my car, but setting the front shocks full soft (rebound), disconnecting the front swaybar (I just remove the passenger's side end-link), and leaving the Cal-Tracs alone (basically set at no preload w/driver) has netted me several 1.5x 60' times on a 26x10" slick.

Good luck! Hope the weather cooperates. Around here it seems the only time I can get to the track is when it's hotter than the surface of the sun.

No wheels up launches but HPP got a couple of bitchin' burnout shots: http://www.firebirdofdoom.com/hpp_big.jpg

Edit: Oh yeah, the Cal-Tracs were definately the key to my combination. Consistent .100 drop in 60' time. I run my slicks at around 13.5psi w/tubes in case anyone cares.

[Nine Ball]

Nice runs Jon! Your times/trap on that article reinforce my confidence that I can get that 10 slip with 122-123 minimum trap speeds. If I can cut a 1.5X I'm definitely in.

[TUBED]

Tony what's the rearspacing on the 15" Weld's up front? Thanks

[Nine Ball]

I'm pretty sure they only sell them in 15x3.5 with a 1.75 backspace. They only make one size 15x3.5, you just have to tell them your lug pattern.
