Also with the tralining arms you will also be able to lower the c of g nicely as the shocks will no long be sticking up in the arm  and its very simple to setup camber and toe via turnbuckles which attach via the trailing arm.
Also for us to run this car in the uk, it can be no more than 250mm wide which i think could be a issue if your using a 4wd front end with rear hubs fitted, and rear tires would have to be fitted at the back of the car for it to be legal.
Btw if you get stuck for making the plastic parts give me a shout. |
Thanks for the advice, and for your heads up on the production of parts
Just a question: Do you think it would be a regretful decision or a mistake (performance wise) if I stick with the double wishbone suspension?
The thing is, I have nearly finished the car now. The reason I have chosen for a regular layout at the back (earlier in the project) is for the reason that I know little about setting up cars - for me it's a way to keep the conventional bit in the car and be able to talk easier with people about setups for this car. However, with the change on the front suspension I guess that's not really the case anymore for the car anyway.
As for the width: I know about the 250mm rule, it is why I have designed custom front suspension arms. I should be able to use 70mm (DF-03 length) universal shafts on the front end, though it will be a tight fit and might require the use of shortened outdrives and/or a gear diff (so I don't have a screw and spring in the outdrives in the way of the uni's).
The wide rear tire rule is a problem though - especially with the current rear suspension
Even though I don't run in the UK, I was hoping the car would be 'legal', I thought getting it less than 250mm wide would have been my biggest issue with regards to the rules - besides the fact that most regulations state it must be run with the 4WDs. It's a strange rule though, why would anyone chose to fit narrower tires on the rear except for when you'd be driving an FF car?
