Do any of u use them and what's the best value for money and where could I get a kit from cheers guys

 

They don't do any harm, but the jury is out as to whether they are any use except on classics, which suffered from poor earths.

You can make your own.
Mine uses thick supply cable, very flexible, bought from an ICE dealer, and a supply of ring terminals bought from www.vehicle=wiring-products.co.uk
You need the ones with a LARGE cable entry, plus mine are all soldered for better contact.

Doing it that way, you get to plan where the cable goes and cut it to the correct length.

Mine cost me less than £10 all in.

A quick search will tell you where to run earths, but most folk do:

Top of each suspension turret, gearbox, engine block, alternator, bodywork slam panel, and one to the bolts holding the ecu in place.

 

ive never thought much about them until recently, my ecu was playing up doing wierd things, i have a feeling this was down to a dodgy earth possibly the one from the battery to the the front panel

 

Cheers lads will have a look
