lol

If you want to keep your exhaust, I would raise it.
Im on standard shocks, and towing a small ski boat and a noot full of ski gear, the towhitch gets pretty low. A car is a fait bit heavier!

Yeah if you plan to tow a small trailer you will be right.. If you want to tow a car trailer you will need to lift it right up..

That sux..:P

Raising it up would just mean that there's more play for the suspension though. It's still gonna travel the same distance to the stops....

I would think that you'd be ok to tow, just that it'd be a VERY harsh ride...

hmmmmmmmmmmmmm unless........ i dog one of my mates to tow me every track day hahaha thats a good idea LOL

i would even try and get your hands on a set of raised springs by king springs

nah it's not worth it that much. I've got King Lows front and rear and I've had a TJ on the back of my car on a car trailer, and no problems what so ever. Not even one lil scrape.

The only problem I can see Jamie is that the car may drive on the bump stops... whether that's gonna cause damage or not I'm not 100% sure... But I think you'll be alright with them, just means that there's not much suspension travel and hence the rough ride.

Bear in mind that towing a Car behind a Magna is illegal. Too much weight.

If youre going to be putting a car on a trailer and your car is that low, expect to have issues with your gearbox after awhile...

The amount of downforce on the towbar (from incorrect level of trailer) itself will be far more than the recommended amount (50kg downforce on the towbar for a magna)

So Bain, would having a trailer with a lower centre or lower axle make the downward weight less on the towbar?

It should yeah.

You could possible go a smaller rim/tyre to negate the issues you would have with a standard trailer. But im not sure on what load rating you would need.

i just shift the weight in the trailer so its very neutral. therfore less downforce.

You can't do that with a car trailer!

Well.. theres the right way.. and then theres your way. :doubt:

lol. I'd like to see you get the car trailer absolutely perfectly balanced. Doesn't the car trailer usually have more length over the front anyway?

Agreed. I'd also be concerned about whether your wheels and tyre combination will legally allow towing.

Im not sure what the towing capacity is on a VS.

Have you checked the rating of the tow pack on the VS? It would need to be rated at least 1.4Tonne. You would also need electronic breaks on the trailer aswell i think (for it to be legal)

Dude what is the weight of the car you are trying to tow? And how far do you need to tow it?

sprinter weighs bout 900kg's ... and be towing it about and and a half hours to mallala all the time ..

i would have thought it been legal as ive seen alot of magnas towing big caravans but im glad u guys brought that up otherwise may have got myself into some hot water

I wasn't aware that there was a legal downforce limit in SA. :confused:

Anyhow if the trailer doesn't have brakes then the legal towing weight is 500kg, if it has brakes then it is 1500kg for the Magnas.

From memory the VS's needed a tow pack to be able to tow large loads, but I'm not 100% on that, be best to ask someone the regularly tows. Or a caravan place may be able to help. Help if it's auto too.

It's not about the legalities about the downforce limit, its how much downforce the tow ball is able to withstand. Generally tow balls can withstand a downforce of 50kg.

Most Commodores with a tow bar should have at least a load capacity rating of 1200kg, I don't think there are any packages Holden offered with a lower rating. However check the label which should be on the tow bar itself.

A 900kg race car with a car trailer the Holden should well be able to handle it with very little issues. Of course I'm not recommending that you regularly do it this way, I have heard stories where a vehicle's body has been 'stretched' after being using to haul heavy loads regularly.


If your Magna has the 1500kg towing pack (or even a 1200kg towing pack if its only a 900kg car) then it will be able to do it. However you do have lowered springs and that will affect the vehicle dynamics but i'm not a physicist so I don't know much more strain it'll add to your drivetrain by adding those extra loads.

I doubt the front suspension will matter as much as the rear though, since the load is practically on the rear and will bring the front of the car up (see my pics in the 1st gen section when I towed another car to see an idea of how much the car will lift, bear in mind I run low's all around).

If you have access to the Holden, you might as well take up on that offer. Just make sure the car trailer has brakes (although all car trailers should have brakes since its > 500kg load capacity).

Generally Speaking, You Can't tow a car on a car trailer behind another Car. The weight of the towed mass is to much for the towing car. If that makes sense.



The mass of the towed vehicle must not exceed the loaded mass of the towing vehicle.

To put it simply, your car must be heavier then the trailer and whatever is on the trailer. Generally a car on a car trailer will be heavier then then the towing vehicle.

He already said the car was 900kg so all up it wouldnt be heavier than the 1300kg+ Magna.

Plus Trailer, Plus Gear, Plus extra tyres. You would be surprised.
