So many variables to consider, these cars are light for their size and have to be driven smoothly.
Things to consider:
Your current setup (tyres, suspension, geo, line taken in and out the corner, when you put the power on and also how delicate you were and smooth transitioning from entrance to exit).
They give lift off oversteer naturally like the DC2 does which is great if you know how to handle it and want that, if not you need to tweak things.
So what tyres do you have?
What is your current geo?
What suspension are you running and spring rates etc?
Personally I love lift off oversteer and generally try to force my car to do it regularly
A car will pitch up when you hit the throttle (the front rises and weight shifts to the back) and pitch down when you hit the brakes as the weight shifts forward lightening the rear as the front dips down.
If you’re turning too early whilst breaking or just after the rear will be slightly unsettled, also as the car rolls leaning away from the corner causing a roll.
With cars If the axis of rotation is behind the centre of the car, the car will understeer. If its in front of the centre of the car, then the car will oversteer.
Oversteer (which you are getting) usually means you unsettled the car mid corner, the only way you can get around the corner smoothly is by keeping the car balanced mid corner which is the key to driving fast and cleanly! When the car is balanced mid corner, it's not over rotating or under rotating and points just where you want it to go!
Don’t go throwing parts at it as you’ll be throwing money away mate
