Is yours a typo or not ?
Also, people have mentioned lengthening the wheelbase to increase steering. I thought short wheelbase meant more nimble, better through tight slow turns and hairpins which is what Worksop is primarliy about and where the car is lacking grip.
Whilst im not saying im right and others are wrong i cant get my head around the logic of some of these suggestions. Im crap at setup and i appreciate the input but need accurate info.
I also cant get my head around how removing weight from over the front axle will increase the front end grip at low speed. If you exaggerate it and say put a bag of sugar over the front axle then im sure you wouldnt be lacking front end low speed steering thats all.
Instinct says short wheelbase, more weight over front axle - i thought that was the idea of the brass bulkheads from the likes of Trish.  |
Mines a typo sorry. I meant to say to run the front end at 23mm and rear at 24mm for example. That will result in more entry steering. Not making major changes in ride height. 1mm is plenty of bias
Weight:
Think of you car running full speed down the straight and you suddenly want to turn left. Which direction is intertia carrying your car? straight forward right? so the more weight you add, the more energy is required to change the direction of that
end of the car. Another example would be to add weight to the rear of the car, you gain alot of forward bite AND high speed steering because when you initiate a turn at high speed the rear of the car is going to want to continue to go straight. Understand? Also by adding weight to the front of the car you loose forward bite quickly, because you slowing/limiting weight transfer to the rear wheels, the buggy will only generate a certain amount of force in attempting to lift the front end and loose grip.
Summary:
more weight = slower weight transfer and slower handling, less weight = quicker weight transfer and will change directions quicker. You can say that adding a bag of sugar on the front bulkhead would provide more grip... but you would have zero rear grip, every setting is a balance. That car with a bag of sugar on the front would never make a turn at the end of the straight, your example should show you how the weight works. Typically adding weight will mellow the car out on high grip, sounds like your conditions are not quite high grip so myself if I were in those conditions i would remove most of the weight on the front and center first and foremost. But thats just me
Wheelbase:
True a short wheelbase (hubs forward) will turn in a tighter radius, so that is a good setting for tracks with alot of 180 deg turns. I run short wheelbase because there are 5x 180 turns and only 2x 90 turns on our current layout
