Review WTF2

I recieved a WTF2 for testing on Regupol.
I tested it against WTF and A-Arm suspension.

The product:
- The finish is as always on Reflex products very good.
- Set screws for king pins. very nice feature. Makes changing preload, springs etc very easy.
- There are made room for using -1 offset wheels with wide range of camber settings.
- Built in camber
- Built in caster
- Nice precision line-up on the chassis

Function:

• scrub are minimized
• Turn-In are increased compared to the first version. I think this is because of the built in camber. The knuckles slides easier on the king pins due to cambered pins.
• On throttle steering have increased
• High speed steering are a lot better. It has a more precise feel
• Turn-in is extreme. It actually has to be tuned down
• The car track extremely straight. i have a feeling that this is mostly because of quite a large amount of caster. Caster helps the car center by gravity

Compared to the A-Arm setup:

• The bump steer the A-Arm setup has are not a problem here
• Scrub. The A-Arm are reducing my speed into the straights. The WTF2 are the best I have ever tried regarding      scrub.

The test tracks:
Track 1: A very technical track with one fast straight. typical gearing with PN33 motor are 9/53. Maxes out at the last part of the straight.
Track 2: A more open fast track. It is 8 meters longer, and one second longer than track 1 in lap time. Typical gearing are 10 - 11/53. 10/53 maxes out around middle of the straight.

The surface are Regupol on both tracks. Grip is very good.
The reduced scrub the WTF2 gives are so important around here. The A-Arm setup kills the speed coming out of the corners.

Also we use the same hardness tires front/ rear, so balance are important. The A-Arm overheats the front tires after 15 - 20 laps. The temperature difference are about 3 degrees celcius. This causes the grip to fade in the middle of the race when you are pushing hard. This is very noticeable when you look at the tire wear.

Lap time with the different systems are not very different, but the consistency the WTF2 gives are incredible. When we are doing longer stints, we can easily manage 40+++ laps that only differes a couple of tenths pr lap when we are pushing incredibly hard.
