Hey guys ,
As I am a green horn, what does a narrowed beam do? And do I need one?
Thanks

Not unless you want to really lower your car, then no, you don't need one.

Narrowing the beam means cutting the front torsion bar housing shorter, which reduces the front track (distance between the front wheels) and puts the font wheels further inside the guards.

I'm not a big fan of them, it's a mod done pretty much solely for looks and doesn't (in most cases) add any functionality. In extreme cases, sometimes the beams are cut down to the point when the shock towers are removed - no front shocks is dangerous.

Having said that, done well it can look pretty good on the right car.

A narrowed and lowered beam can also give tyre clearance issues meaning you have to fit thinner and lower profile tyre than std.

Only real reason apart from looks is for LP beams running brake disc kits. These increase the track depending on the kit bought and so narrowing the beam helps rectify this.

So in answer to your question " do I need one" No you don't, that is unless you are going super low but the boys in blue frown on that look nowadays.

Most narrowed beams will have a shock tower and new end plates, if you do choose to do one my advice is get a scratch built one.

Make sure any mods for your vehicle are legal and engineer approved, a lot of people have cars fitted with a narrowed beam but it is not legal to narrow the track, i just removed a narrowed beam from my ghia and there is very good improvement in the handling and ride department. i think the lowest ride height allowable is 100MM

I believe, from memory of reading the NCOP, that the track cannot be modified by more than 25mm in either direction. Been a while so could be something else it related too but fairly certain was the track width 🙂

Lowering cannot be more than a third of the distance between the top of the bump stop and it's point of impact on the chassis or suspension component. Tho the minimum ride height is 100mm to lowest point on vehicle.
