It will make more downforce with less drag. We’ve done CFD testing of both on the car and it’s not really close. I’ll be switching to the V1X for next season and selling my Spage wing.
One tuner, who is mentioned multiple times in this thread as being great, gave me an awful tune that resulted in tons of surging and instability. The car literally bucked around so bad under partial throttle that it would break the rear end loose through corners.
I tried to get them to fix it...
I’ve used 3 different tuners, all of them were highly recommended and very responsive. They all had a lot of experience with tuning high hp cars and tuning track cars.
All of them got about as much power as you could expect out of the setup, but only Zach @ CSG achieved 10/10 smooth power...
I ran the RSL 1 on my rear axle once and managed to overheat them in 3 laps at ABCC. RSL 1 is a higher friction and more heat tolerant pad than RSL 29, so I can't imagine the 29 would withstand many laps with grippy tires or on a car with much hp.
Idk how so many people have issues with pad compounds. Drive 2-3 fast laps without triggering ABS and every pad is going to be smoking hot and pretty well bedded in my experience. The “do a few hard stops” strategy is usually just not enough (although it’s a good start on your outlap).
I ran at...
Lowering the car messes up the rear toe curve, ie it changes the way that toe changes through the range of motion of the rear wheel (yes, this is called bump steer - your wheels changing direction under bump)
As @razorlab pointed out, the rear toe and traction arms can be replaced to correct...
