I would think the wing is going to be the most laptime gain at most every track?

 

I would guess so, but my goal isn't 100% lap time as much as overall car balance and controllability. I'm worried about those 60-90mph turns where I could now run into snap oversteer and hit the inside guardrail. Am I better off with the wing or with the swaybar? I"m thinking the wing, but hopefully someone with a wing can chime in if they make any difference in that 50-60mph range... 80+ I think its established that the wing is a benefit.

 

wing makes a difference at speeds as low as 40mph. This has been proven at slow tracks like like Streets of Willow Springs in SoCal. Even at a track like that, the wing is faster - many other drivers site the same experience (myself included).

 

Food for thought.... a wing may help deal with the symptoms you're having, but why not deal with the problem that is causing the symptoms...

Aero should simply improve an already solid platform IMO. Adding aero to balance a poorly set up car is like boosting a worn out engine because its lost power over the years. Yes you have gained the power back and perhaps maybe even gained some, but you still have a worn tired engine which will fail at some point.

I know budget and time are a factor hear, but just something to think about...

 

I understand your general point, but I don't think it applies here unless you are saying that a square tire setup is now considered a poorly setup car. I'm sure there are a number of people here who would argue against that assertion. I haven't had the chance to push the car to the limit this season yet so I don't know how bad it is going to be, but there are enough people here who run 255's on all four corners (particularly at the track) that I was hoping to get some guidance on what others have done.

 

I think he was getting at my first post... Essentially, dial in the suspension and use the wing to enhance it.

 

I am not saying that a square tire setup is poor, my personal car, and the race cars I've set up run square. However, if you had a suspension 'setup' with springs and sways on staggered wheels and tires that felt good and to your liking, putting sqaure tires on the car is going to through the balance WAY off. You need to increase front roll stiffness (however you choose to) or reduce rear roll stiffness. Either way the car can and should be neutral without the use of a wing. With that much tire I would suggest a decent amount of toe in in the rear as well.


Couple of questions to help understand your oversteer issue

What do you currently run for an alignment?
Where are you getting oversteer? Turn in, steady state, exit....
AP1/AP2?
Do you have adjustable anti bump steer toe arms?

 

^ He has an 07 on kwv3. So it's not an oversteery setup. A BSK would help but not as much as on an AP1. Maybe toe is an issue with the added power?

OP do you have pics of your car? Curious to see what ride height you are running, alignment settings, and shock settings if you mind sharing? I've run your setup before countless times and it is not a massive over-steer inducing setup at all. I don't think the answer here is larger front bar. It could be a lack of rear grip and your right foot being too heavy

 

Square tires, with square springs and stock sway bars is going to be pretty oversteery. BSK does nothing on an AP2.

 

OTC v3's? He could have them revalved with way different spring rates. The more info we have the better we will be able to help. I agree with you in the fact that in theory his setup should not be all that wild, unless the alignment and shock settings are way off.
