dropped a boll....
jossey - 16/9/13 at 06:25 PM

So after rebuilding the front of the tiger from the crash.



I got everything done, including the new bones provided by Mac (snakebelly)

So I started setting up the camber etc and I noticed I could not get the the camber into negative numbers......

Well after stripping it all down and getting angry at 9pm last night it turns out the wishbone brackets I bought are incorrect. the bolt hole is 13mm higher than it should be which pushes the top of the upright out and the bottom wishbone too high and it messed everything.

So here is my mistake.

New wishbones bolted in. I tried to set the set the camber up. Fully adjusted even with the draglink bolt removed left 1-2 degrees positive camber. SOMTHING NOT RIGHT 6pm (cold sweats start)

After checking everything out and the tiger book for wishbone locations (checked and are right)

I noticed the wishbone brackets I bought are the 44mm locost ones bent to the 38mm size so the hole is 13mm too high meaning the top is pushed out by 13mm

so I unbolted the wishbone and pushed it in by 13mm and then un screwed the drag link and SORTED.. SO i just need to strip the brackets off and get the right ones.

So mac is going to sort me some brackets and ill have to cut it all off and start again with the brackets.





AHHHHHHHHHHHHHHHHHHHHHhhhh

Did the photos have to be life size ???

Should the brackets not be a bit lower aswell. I'm sure on a locost the top wishbones are lower at the chassis end than at the upright end which also helps the give the correct changes in camber for when the body rolls aswell.

Not on the tiger they have to be level due the width of the chassis they are as tiger designed then.

Sorry about the life size pictures

You could slot the holes in the brackets and then weld washers in the appropriate places to locate the bolt.

Ye mac mentioned that but given the extra work to do it right I just Makes to sort it properly my car is still not gonna be ready for at least 6 months so why botch it......

Ill bite the bullet

The tube for the top joint looks very long, could you not simply take 10mm off the end of it & finish up with the same result for a lot less hassle?

That is going to change the suspension geometry (i.e. shortened top wishbone mounted further out from chassis), though whether it will make any noticeable difference on the road is debatable.

Agreed & if it was a race car, it might make a difference (might be better, who knows), on the road I would be absolutely amazed if there was any noticeable difference at all, & again, might even be better, 7 clone suspension is far from perfect!

The bones were designed to bolt straight onto a Tiger and with that in mind with the right brackets they will give the correct range of camber, i did do a set with a slightly shorter top tube but there wasn't any real benefit and the extra machining required (the top adjuster is bought in) was an extra cost.
Unfortunately like all things Tiger the brackets aren't standard.

I had exactly the same problem with my Panther, it turned out follwing advice from on here, I had Sierra bones and Cortina Uprights, although I ordered Cortina bones I did not get them.

I changed the Cortina uprights for Sierra ones and everything lined up.
