got my rising fighter front suspension parts today......the suspension arms dont fit :cry:
they foul the chassis at the front. so i guess i will have to get the dremmel out and grind off part of the chassis. right where my finger is pointing........

How weird is that. I had no (real) trouble on my Hopper :



Could you maybe take a picture of the side? Before using the Dremel... :S

it was just catching it, i have taken 1/2 a mm off the back pivot, so the arm sits back in the chassis slightly and just reprofiled the front with a file and it seems to clear ok now :woohoo:

and as a bonus the parts that come with the arms, there is a set of bottom spring cup thingamejigs which fit the springs on the CVA's you sent me. just need to cut off the ball joint bits, drill a hole through the centre, to fit the piston rods on the shocks, then screw the new metal ball joints on. rear shocks...SORTED :woohoo:

and..............here it is, completely cobbled together at the moment as i still need to get the proper screws and longer steering arms, but you get the picture! (pun intended!)
i think the shocks need to be on the slightly taller setting as the wheels dont sit flat on the floor, plus i'm wondering if the front is actually too wide now :S

I don't know, ludicrous camber angles were all the rage in last years F1 & British Touring Cars :whistle:

I like the ultra wide stance. But you could go back to the normal Hopper steering blocks if it's too much for you...
Or put some wheel spacers in the back wheel (possibly 2mm) to match them more with the front.
The shocks look beautiful - the tension is (ring) adjustable, right?
You can see what angle the arms naturally are by lifting the front and letting the wheels hang free.
Then you could determine if you need to add more spring tension or create extra overall length on top of the U-bracket.

yeah it works well on tarmac racing but i reckon you need more tread contact when on the dirt
