Race car getting ready part 2

In the last episode we discovered that I really needed a better suspension. I managed to find a KW rebound adjustable suspension front and rear for a good price. I also renewed the front control arm suspension joints with Meyle HD items and I replaced the stock bushings with eccentric polyurethane ones.


The car was feeling loose in the rear so I designed some solid steel rear subframe bushings. This makes the car predicable and crisp and also raises the rear subframe 6mm to improve the rear roll center.


It all fitted like charm.


A simple trick to improve steering lock is to add a shim to the steering rod.


The stainless steel shock body does look really nice.



The exhaust sound was too muffled and made  a wooshing sound like you hear on newer cars, especially Audis, so I made the cheapest sport "muffler" ever, a 60mm piece of pipe.


Now the engine breathes better and sounds a lot better if a bit loud.


I tried to raise the car a bit, but the suspension adjustment rings are stuck solid. I tired to persuade them in every way but they wouldn't budge. Here's a picture with the car running rally slicks on the front tires.


The kill switch needs to also be accessible form the outside, so I decided to fit it near the lower part of the windscreen. It needs to be attached quite sturdily, so I made an aluminium bracket for it.



The fitment is perfect!



This is the way I installed the kill switch in the center console, I also made a bracket for this. 



Then my attention turned on the fire extinguisher, the mounting bracket and the extinguisher came RRS and they are up to FIA spec.


This is the way I installed the handbrake, a wilwood item with a homemade 600mm lever.



The interior is done!



My friend you see here managed to get us back on the carting track.



This time it was much, much better, the car handled way better, although I think I'll need some stiffer antiroll bars.



The better suspension gave me more confidence so I started to push it. I was able to raise the entry speed to about 110 km/h 



I naturally pushed the car even faster, but I ended up in the kitty litter big time..


A few videos of the day:






 Next up I'll try to enter a hill climb event and after that swap the engine for something with more oomph.
