1) can't really answer cuz I am more of a twisty back road guy.

2) When you have a adjustable suspension, it is critical and very benificial for a corner balance. Corner balance will make sure that your car is level from left to right and front to back. And by adjust the preload on the each supension, they will try to get you diagonals to be equal to each other. weight of FL + RR = ~ FR + RL. This make sure that the handling feel and capacity of the right hand turn will be very similiar or equal to the left hand turn.

3) When buying nice coilover system, the shock valving is setup to for their specific spring rate; where else if you buy a shock and a spring seperate, they might not compliment each other too well (not design for each other). There are quite a bit of autoxer and racer that get custom spring rates and buy Koni shocks and get the shock revalved to match their spring rate.

So, "AP1Racer" is posting in the Racing & Competition Forum, but doesn't know his lap times because he is "more of a twisty back roads guy". Hmmmm.

1) It all depends on what modifications you are talking about

2) I suggest you read up on corner balancing; it's a completely separate thing from F/R or L/R distribution.

3) It's easier to buy a pre-engineered coilover than it is to do your own mixing and matching, but many folks in this forum do do the latter.

1) I can't say because unless you test them in a controlled environment it's just guesswork. You notice the difference in how the car behaves in cornering allowing you to carry more speed with better composure. Traction comes from the tires but a more optimally tuned suspension will do a better job of keeping the contact patch on the pavement.

2) corner balancing is equalizing the cross-weighting. Think of a chair with one leg shorter than the others. When you can adjust the preload and the ride height of each corner you need to make sure all the legs exert the same force on the ground (weigh the same) when you make changes to the ride height. It's actually difficult to do and requires someone skilled and that's why it costs $$$.

3) coilovers are shock/spring combos which have been paired. It doesn't mean you can't replace the springs what come with so long as the shocks are valved to support the spring rates you want to use. There is usually a pretty wide range that the shocks will support. Coilovers are just ready to install kits.

With my s2k, since I just got it 2 1/2 weeks ago, I been wanting to take it to a any track event, but can't due to lack of time and money. The twity back roads is def a better option for me right now. The reasons why I can stand by what I wrote is that I am a 3rd year engineer and am taking a class on vehical dynamis and suspension for my tech elective. Also, I am a member and top driver of my University FSAE team. We have also taken the SAE car to get it corner balanced at this Porche Racing shop which is owned and operated by our advicesor who also teaches the Vehicle Dynamic Class.
