Now that we've had a chance to get a few events in this season, I wanted to see what alignment and set-up the die-hard racers were running for autoxing.

Are you running stock suspension, sway bars, aftermarket springs and shocks, or coilovers?

What kind of tires?

Have you changed your alignment? Front camber and toe? Rear camber and toe?

What are your swaybars set at if they are adjustable?

What is your suspension set at if it is adjustable, front, rear, height?

I'm running stock suspension with Kumho v700 for race rubber. I have been running stock alignment with good results, but I'm going to try something new this weekend.

I'll be trying -2 on front camber with just a little toe out and -1.5 rear camber with 0 toe.

If we get a little info sharing going on we might be able to help each other out and get some tCs to the top of the class in the process.

I wour run as close to zero rear camber as you can, it will help the car rotate better.

The front alignment sounds pretty good, if your tires are not rolling over and are the same temp accross the tread then i would try a bit less camber fore more traction out of the turns.

I am running -2 up front and -.5 in the rear, I am going to try -1.5 up front next since my tires do not roll even with pretty low air pressure. Toe out can really help th ecar turn in quicker but can reduce forward grip a bit so be carefull with that and especially after the event when on the streets.

For now my Hotckiss bars are at the mid setting in the rear and soft up front. I am going to test some extention brackets to make the front softer yet and see what happens.

i second that
i have noticed with my front end adjusted, messing with the toe i corner tons better, but if your on a track with alot of str8s, its not going to help.
but since the courses i run mainly are corner heavy, having front/rear camber is a bit helpful with my grip

 

Thanks for the input Rick and ScionBandit.

We setup my car with -1.5 camber front and rear with just a little toe out.

Turn in is much better but mid corner understeer is still there on slow and medium speed turns.

I'm thinking -.5 to 0 camber for the rear might help get the car rotated a little better in the slower turns.

Lift throttle oversteer in the higher speed turns is still there when I need it, So I don't want to mess with that to much.

So far this setup is working really well. I've come in second in my class and PAXed top ten several times. And I finally finished 1st in class and 1st overall in PAX for the 1st time.

I think I'm finally getting comfortable with the current setup, but I still want to fine tune the car a little and my driving skills alot.

 

glad my little input helped, i haven't gotten out as much as id like to this season, still working on the car and finishing the project, should be up and running full strength next may (once my parts,paint,etc. gets done)

but i will post any more input if i go out again this year (which i should)

 

I'm really glad I decided to stay in HS class. I can't do as many things with the car (which is good and bad), but it has really let me focus on my driving instead of having to focus on the car.

There is something about getting alot out of the car with being able to do very little it from a modification standpoint.

 

i agree, but my goal for the car is to turn it into track-only vehicle
i know this will take time,effort and money but i am working with Scion to get something set-up

but i rely HEAVILY on my driving skills, and i hold my own for FWD going against mainly RWD cars

 

Bandit,

What setup have you be using?

 

I'm bringing this thread back to life, in an attempt to find out what alignment everybody is running for the 2007 season.

It would be great to get a feel for alignments that seem to work or not work.

I plan on testing my current set up at a "test and tune" in the Cincy area on Sunday.

My current alignment is -1.6 front camber with .04 toe-out and -0.6 rear camber with 0.0 toe. My Hotchkis FSB is set to soft and the rear TRD is set to track.

If this takes car of my understeer problems, the next thing to focus on is putting more power down on corner exit. I may have to put the stock FSB back on if the "soft" setting on the Hotchkis isn't "soft" enough.

Is anybody here running just an upgraded RSB and stock FSB?

 

At my last event in the tC I ran with the FSB disconnected.

But, I had 245/45/17 V710s, LSD and allot less top heavy than other tC's.

More negative camber up front will get you more grip into the turn but less coming out.

Toe sounds good up front.

You could go to zero rear camber and a bit of toe out but not fun on the way to the event with toe out.

As for the FSB disconnected, it is worth a try

Rick

 

Thanks Rick.

Do you remember what tire pressures you were running on your V710s?

I thought you were selling the tC. Did you end up changing your mind?

 

The buyer was not able to get it, I waited for months and then winter hit so waiting until spring now, this cost me allot of money but such is life, I really wanted him to get it.

Sorry, no idea what I ran in them, probably pretty low if I recall but you may have to check some autocross sites to get some help there.

Rick

 

Would you want to sell the V710s?

 

what would you guys suggest as far as alignment specs that would help me out on the track, as well as not destroy my tires really quickly?

on my old civic, i asked on the forums and got some specs and had it aligned to said specs and was really happy with it. i have them written down somewhere, but they're not relevant since i don't have the car anymore. any help will be appreciated!

thanks

 

Are you still staying in HS? Correct me if I'm wrong, but I was told you couldn't run a fron sway bar adn still stay in HS...

 

Yep I'm still in HS.

Well sway bars get interesting when it comes to the tC.

In Stock class the rules state that the front sway bar is unlimited. You can run whatever you want, stock, bigger, smaller, or no front sway bar at all.

Now the RSB is where the tC takes advantage of the rules that allow for factory/port installed options. The TRD RSB could be installed from the factory/port on the 2006 and 2007 tCs. It has to be the TRD or the Stock RSB no substitutions. I've talked to the SCCA SEB and Jack Burns who came in 3rd in HS at the SCCA Nationals this year and both say it is legal. In fact since Jack owns a tC he asked me to make a copy of my window sticker in case he decided to run the tC some time down the road.

So to recap, FSB no problem, RSB you better have your game straight because people may challenge you to prove it but it is legal in stock class.

 

Ahhh, I stand corrected. Thanks for the info.

 

Well based on our Test & Tune yesterday I've got to say I think we are on the right track with the alignment settings. The tC felt great, it was very easy to trail-brake into a corner and get the rear to come around allowing us to get back on the throttle earlier. The small amount of toe-out up front really helped with initial turn-in. Over all the car was very playful with almost all of the painful understeer tuned out.

We decided not to run my race-tires because of the below freezing temperatures. As a result of not have my race-rubber on we couldn't get a good feel for how the car was doing getting the power down at corner exit.

So far I like the feel of the new alignment, but that "feel" may not translate to lower lap times. I should know a little more on the 18th at another T&T. I hope it's faster because it sure is more fun.
