newbie questions chassis
hello everybody,
after buying the Ron Champion book I searched the Internet and found this forum. Props to everybody here. Your guys experience and motivation is a
bless for every new builder.
So enough praises. 
How long does a chassis in race use last?
What is the total weight of a track car? ( I know a general question and not an easy one to answer due to the countless possibilites)
What kind of slicks are you guys using? Some experiences with Formula Michelin slicks 13". I know Avons. What about Kumho, Matador, etc. ?
if itīs been done donīt do it

welcome to the forum! Cant help with the rest, but the chassis will last until you bend it, there are no fatigue issues with a steel chassis.

Hi as said no problems with the chassis for racing puposes. But there is room for improvment on overall regidity if no regulations.
The locost championship in the uk uses road tyres yokohama A539. This championship is for cars built to the book using the 1300 kent engine producing
90BHP so in terms of grip for the power the tyres work well.
There may be other people on here who have expirience with the book car using slicks.
The other two championships where the locost ussualy runs is in the RGB and KIT CAR championships.
RGB is for bike engined cars and the KIT CAR is for car engined cars but both championships run on yokohama A048 tyres.
Weight wise if there are no regulations on minimum weight a book type car can be built with a bike engine as low as 400 KG. And with a car engine As
low as 480 kg. All dependent on engines being used.
cheers matt

Hello, welcome to the forum. You'll find a very helpful bunch here.
If I can give one piece of advice I'd throughly research the car before you commit to anything. I have had to have some very expensive (money
and time) mods to make my car up to race standards.

thanks for the information
frst thanks for the information and I would say any advice is good advice. I mean this positive because Iīve learnt so much just because of
listening.
Anyway my plans are like this.
First built a fairly normal spec car from a given donor. Getting some experience and a feeling for the build.
Then I would like to build a turbo-charged BMW powered, IRS track car. Mainly for autocross and hill climb races.
In this version I would like to test some suspension set-ups, kinematics and even simulate them. Studying automotive engineering helps me here.
Finally building a bike powered turbo charged open wheel single seater, for hill climb races.
I guess it is quite embitious but thatīs what Iīm interested in.
Please continue posting.

your approach is perfect, aiming for perfection first time will just be annoying, my first car was shite but worked, my second was messy but worked,
my third will be a monster!
