2006 Range Rover Sport 4.4 V8 HSE Java Black

Weights preventing installation of new exhausts.

Purchased a set of Quad exhausts. Took them to the bodyshop to install. After several hours and attempts, the supplier advised the bodyshop to remove the factory installed weights hanging under the RRS which were preventing the exhausts from fitting properly. Should I allow this? What are these weights there for? 2006 4.4 HSE, Java black, Alpaca beige int, super charged grill and vents, dvd headrest, fridge, bluetooth, etc
Fully colour coded as per overfinch spec.
Overfinch twin exhaust tips, 22" overfinch supersport wheels.

2006 Range Rover Sport TDV6 SE Arctic Frost

They are called "harmonic mass dampers".

I wouldn't allow anyone to mess with them. Even if they are moved slightly to enable the exhaust tips to be fitted, they could end up knocking against the rear bumper or the newly modified exhaust system which would give you a horrendous noise inside the car. Arctic Frost TDV6 SE. Aspen Leather, Cherry Wood, Privacy Glass, PTI, Tow Pack, Mudflaps, Tasmods, a new Fuelflap, a RRSport.co.uk umbrella in the boot & a RRSport.co.uk sticker on the rear glass.

Oh my... Are they the reason for this car weighing extra 400kilos over the competition?

They're used to stop unnecessary vibrations damaging the car over periods of time - a lot of cars have these, but not always quite so obvious. Don't get anyone to move them - it will all end in tears

They are fitted to all RR Sports and Discovery 3, nothing to do with the dynamic response.

I'd be surprised if they weigh more than four kilos never mind anything like 400 kilo. I think the extra weight has something to do with the big black chassis that the weights are bolted too.

Lets put it this way, if they weren't necessary you can bet Land Rover wouldn't have fitted them. Leave them well alone. 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it
2018 Melting Silver Mini Countryman PHEV - soon to be replaced
2015MY Corris Grey SDv6 HSE Dynamic, the best car I have ever owned, totally reliable only a cou0le of rattles in 3 years, now no longer in my care
Also in my garage is a 1996 TDi300 Defender 90 County HT made into a fake CSW

Will have to see if fitting a set of these will make any difference!

There is a link from one of the posts on the RRnet thread about the weights which was how I found them! 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it

2008 Range Rover Sport TDV8 HSE Java Black

Id go with vibrations.

Now im no engineer but....

I was just watching this documentary on the Burj Al Arab hotel in dubai. When they wind tunnel tested the building they realised under certain wind conditions something called vortex shredding happens (mini tornados are created as the wind goes around the building which can cause great vibrations/pulling force on the panels which can eventually shake a building to pieces). They used suspended weights in the exoskeleton to counteract it, which just reminded me of these weights . So i would assume that maybe the same conditions can be replecated on a range. Especially at the higher speeds?

Either way even this theory comes back to vibrations
