Better be for the price 😬. Just hoping I've chosen the right ratios. *eek*

 

So what ratios did you go for ?

 

I was looking at these the other day , ruled out the box with the 1.1 top ratio , the other two are the same bar 6th . Caterham are using the longer legged top version in the 620R

Aye, there's not a huge amount of difference between the taller two. I chose the same, with the tyre size and diff ratio we entered came out to 1st as 67.7mph and top 169.3mph. I think I got the front and rear sizes mixed up though.

 

 

1st 14 29 2.071 67.6 20.34

2nd 15 24 1.600 1962 87.6 20.0 2.564 2.564

3rd 20 26 1.300 1611 107.8 20.2 2.089 2.082

4th 21 23 1.095 1354 127.9 20.1 1.76 1.753 -0.2

5th 20 19 0.950 1143 147.5 19.6 1.521 1.514 0.1

6th 29 24 0.828 1109 169.3 21.8 1.343 1.332 205 0.5
