Lunchbox Four Link Monster

[Cephas 490]

I have seen a number of people use the technique I am going to try, always wanted to do a four link on a Lunchbox.

I am going to use a number of Monster Uk upgrades to make it all work, hence the Monster reference in the title.

Using the D7 parts to make the front mounts for the four link is the start.

Next I used the Monster Uk rear suspension mount and flipped the axle over so that the old axle mount becomes the wheelie bar and the carbon fibre mount becomes the new mounting point for the four link

Next the panhard bar, had to put a spacer in one end for the suspension mount to clear.

all seems to work smoothly without any binding, needs a bit of fine tuning, but happy with it so far.

I modified some generic crawler shock mounts to use as bottom shock mounts attached to the carbon filter four link mount

Nice project - will be watching this thread with interest.

Is the idea behind the 4 link rear end to improve the handling?

I’m pretty @Saito2 has modded his LB rear end using a 4 rod link set up. 

[Cephas 490]

Yes that’s part of what sparked my interest in trying it, as I have a stock Lunchbox.

Somewhere I saw one that had used the stock gearbox/ axle and just flipped it over, that and Monster Uk are making some good upgrades for the Lunchbox. 
so I am adding it all together in one.

I am interested to see how it will handle 

[Saito2 5616]

Good memory @Grumpy pants. It will handle better, probably the best it possibly can while still retaining a solid motor on axle design.

Put the Monster Uk front end together today 

 

[Cephas 490]

It’s well made, changed the plastic tie rod ends for alloy ones I have spare

[Cephas 490]

I was going to use the upgrade from option1 to replace the stock A10 part, but the fitting is not great, so I went back to the stock part for now.

Front end is complete, much better than the Ampro one on my other Lunchbox.

seems to have made the front track width slightly wider than the rear, unless this is normal, not an issue as I was looking to widen the width anyway 

[Grumpy pants 3932]

Looks good, interesting that is it better than the Ampro set.

That front end looks better than Ampro or the old FX10 conversion...... The burning question, is it terribly expensive?

Considering that it's for a entry-level kit....

[Cephas 490]

It was £50 so depends on what you call expensive, for a Lunchbox probably but considering how far I am taking it, for me not really as I don’t build many cars in a year. For me they have to be a runner ( which this one will be ) I limit myself to 5 runners at any one time or a shelf queen of which I have 2 and room for 2 more.

Almost finished

Just some soldering to do.
