More camber please!
After the understeering mayhem of the Dunsfold Handling Day, I decided a few minor adjustments were required to improve turn in and front end grip in preparation for Dad's Day Out in June. Armed with some googled facts, I set about the car with some spanners! To do:
1. Increase negative camber - the theory is that the harder you corner, the more negative camber is required to maintain a good contact patch.
2. Add a little toe out - I didn't measure it, but I had a feeling there was a little toe in - a little toe out should improve turn in.
3. Increase the rake - thus shifting the weight of the car forward a touch. As I sit a long way back (as far as one can) and so does the passenger, and as I will have a passenger for the whole day at Dad's Day Out, I will need to dial in a little more rake to compensate for the passenger and let the tail be a bit happier!
Another major consideration was the tyres - the handling day proved just how bad they really are! On the road, limits are not pushed or even close to being pushed, so the rubbishness is not really noticed. However, once the car was shown some tight corners at higher speeds, the lack of grip became very noticeable. As a set will set me back £300, I shall have to see how finances are closer to the time...
I started out by tackling the easiest tasks - 1 and 2. Jacking up the front, I whipped the front wheels off and popped the joints. I decided to give myself 1.5 extra turns of negative camber on each side, which roughly equates to 1 degree. With the rose joints, the whole job took very little time (the second side only took 5 minutes) and I dropped the car back on the floor. As increasing negative camber also induces a touch of toe out, I decided to leave that until I had driven the car.
Unfortunately time wasn't on my side, so I put the car away again, but before I called it a day, I pulled the NSR stop light out as someone had kindly informed me it had gone! I was greeted with this pretty little thing:
Unfortunately I didn't have one to hand, so I'll have to run to the shops and get one.
Next time I will be looking at increasing the rake. I have two options - lower the front, or raise the rear. The rear platforms are already as high as they will go, so I may need to move the circlip up. However, it is mightily tempting just to lower the front, as it's easier to get to and less faff! Choices choices...
