Great experience today at Adrenaline Racing in Lake Oswego, OR. Eddie (owner) was very patient and took the time to answer all my questions. I told him I'm not very knowledgeable about suspensions and especially lacking when it comes to dialing it in. I told him I will run track events, a couple of auto-x, and plan to run the Silver State Classic.

Based on the information from the Q&A, he set my car up for mainly track and high speed.

nice man... notice anything on the drive home?

I am going to guess someone, or weights, were in the drivers seat when you did this. If not your car is heavy.

Those numbers all look great however you should have a little rear toe in for the road course and the Silver State. Zero rear toe is ok for autox but at high speed you do not want the back end loose. Also some toe out in the front will help turn in for autox and the road course. You can have the tie rods and cams marked with paint so you can change them for what type of event you are going to do.

ULLLOSE,

Heavy? Really I thought the GT cars on here were around 3100lbs. FWIW I had 3/4 tank of gas and the spare tire in the trunk. I will definitely let them know about the rear toe though because I do not want the rear more prone to breaking loose. Great tip about marking the tie rods!

whoneedspistons,

Driving home last night the car felt great. I took a few long sweeping turns and sharp corners and the car felt very smooth, balanced and planted entering and exiting. Braking felt better too but maybe that was just me enjoying the drive home so much.

I agree....you want a little toe-in on the rear, otherwise you will find you loose the rear end
( turn 6 at Portland ).

What PNW events do you plan to do this year? It would be nice to have a few fellow RX-8's out

Yeah GTs are heavy....

So they did not have you sit in the seat or have weight in the seat when they did this? Did they unhook the swaybar end links? If they did not have the car weighted for a driver and unhook the swaybars the corners weights are off. The car must be set up with driver and swaybars have to be unhooked to prevent preloading of the suspension. Without these two steps the weights can be off by a good margin when you get in the car. You really need to be in race trim, no spare tire or extra weight, when you corner weight.

based on the info provided I would probably steer clear of using them again ....

so what speed class are you running for the SSC?

Working my butt off with the hopes of getting to the SSC in Sept this year but as with all things, it is coming down to $$$$. Lots to do with the car and unfortunately the house needs a new roof ($10k-$12K) and siding ($7k). Since this will be my first time and a lack of racing experience, they want first timers in 110 and below. If all goes well and I enjoy the event then I will come back to participate in a faster group.

What is it you do not like about the corner balance numbers? Keep in mind due to my lack of experience with suspension tuning, I probably did not properly relay what I needed. Based on the responses here, I see that I should have removed the spare. One thing I left out in my initial post is that I told then I do not want to burn through tires in less than 10K miles. Not sure if that makes a difference in your thoughts.

It will be my first time driving at the track so I plan to take a driving course and sign up for track days as time permits. It would be cool to run with other RX-8's though! Are there scheduled track days with other rx-8 members? How many events/track days to you participate in?

dannobre

iTrader: (3)

I did 18 days last year....probably will do a few less this year....busy at work and a lot of the days seem to be Thursday this year

Would love some RX-8 company

the corner weights are good, they got the toe settings backwards (swap front & rear toe settings) and like Uuuloser pointed out, the lack of driver weight and endlink info concerns me

ULLLOSE

iTrader: (1)

The car does not drive down the road empty. By corner weighting without a driver when you now sit in the seat the weights will be off. Also by having the swaybars hooked up during the weighting process you numbers are not accurate because the swaybars transfer weight as you raise or lower one corner of the car. The ideal setup is with driver in the car, fuel set to race level, spare tire out and swaybar endlinks unhooked. After the corner weights are set you hook up the swaybars using adjustable endlinks so you have no preload on the bars, you should still be in the car at this point.

With out doing all of this you might as well of saved the money and just set your ride height in the driveway with a tape measure, you are no better off now then you were before you had it done. This is very basic suspension engineering and I am surprised these guys did not do/know this.

ullosse/team,

Great info and I will relay it to AR to see what they say. Having said that the car drives great on the street but obviously it is not being pushed hard.

Do yourself a favor before you call them, call an actual race shop that build cars and ask them how they do it. Those guys are going to tell you they did it right no matter what. From what I see on the website it looks like this place is tuner shop with no racing experience other than a few track days. A place like AWR, MER or Tri-point that builds race cars will give you the real low down. If you are armed with some solid info you might have a getter chance of getting them to redo the work right for free, like they should.

I'm not saying they didn't do it, just that the lack of info is troubling, coupled with them giving you front toe-in and zero rear toe makes me less than comfortable ...
