Title: Question regarding rear camber?
Post by: Raj2212 on February 03, 2018, 02:43:04 pm
Hi, after some advice

Finally got some spacers to put on.  :party: :party:  I've gone for 12mm spacers for the rear and leaving the front for now.

Would the rear wheels have added camber when the spacers are put on. Or is that done another way. I was looking to add slight camber to the rear wheels to stop them from hitting the arches once fully loaded.

Any help would be appreciated.
Raj

I don’t think putting wheel spacers on will change the chamber of the wheels. I’m pretty sure there are some accentric bolts on the rear arms you can adjust to change the camber on the rear wheels but you probably want them to be set up with the correct equipment. Just eyeing the wheels up might make the car drive a bit funny.

Thanks for clearing that up @Graham1990 (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=24678) . I'll have a word with the guys that did my alignment to see if they can do it.

Don't really wanna compromise the ride. Would it be best to leave camber alone??

If the tyres don’t rub on the arches I would personally leave it as the vw settings say so. But a little bit of negative camber shouldn’t effect the ride or the way the tyres wear to much if they are rubbing on the arch. 👍

In my experience the 12mm spacers you've gone for Raj should gIve you a very nice stance at the rear without inducing arch rub. Strangely, on a previous Ed30 I had a 15mm (each side) spacers caused a world of pain in terms of rubbing and after a hunter wheel alignment, I discovered the rear sub frame was out by 6mm or so to one side.
If you want to add a small amount of camber you can buy camber bolt kits but I doubt you need them at 12mm.
I have 12mm all round now on my current Ed30 and it sits lovely. Just remember extra length bolts!

I have rear 15mm spacers on H&R springs......no rubbing yet

Mannn load that camber on, I'm running -4 degrees to tuck 9.5J wheels. You'll be fine with running -2 to -2.5 degrees without having excessive inner tyre wear.

Running 12mm h&r spacers on the rear, no rubbing and no need to adjust the camber

No need for more neg. rear camber, but you have just increased its understeer...so careful until you have become accustomed to it...if you challenge your Beast.  :drinking:
Easiest thing to do to reduce understeer is raise front tire pressure and lower rear tire pressure.
A stiffer rear ARB works.
Smaller front tires or taller rear tires may help.
More front neg. camber would work if you install a front adjustable camber kit.
But if just a daily driver and going for turning heads...the above should be ignored.  :happy2:

I think you meant it the other way around.  :happy2:

Thanks for all the responses.  :happy2: :happy2:

Found some time to get the spacers on the car.
I've chose to leave the camber how it was for now. Love how it looks now and drives fine.
No rubbing  :happy2:

10mm spacers on the front now  and it will be sitting pretty much as good as it gets then

That would go against everything I have ever been told , read, or heard. I always run 2 lbs. less air in the rear. You have any documentation stating I have it wrong please?

I'd recommend you guys have a read of this, best explanation I could find. Few posts down

Good reading.  Coincidentally, I've been experimenting with tyre pressures recently and it doesn't come as much of a surprise that it rides and handles best on the factory pressures written on the petrol flap  :smiley:

Funny that. You'd almost think VW spent a bit of time sussing out what works best  :signLOL:

Being more used to 90s VW tyre pressures around 30 psi, I was stunned when I saw the MK5 needs 2.6 bar!!!   It works though  :smiley:

I thank you...was for a moment thinking I was wrong all along in my own set up. My suspension travel is quite limited given I have both front and rear H&R ARB's...and still can push a little if accelerating a bit through corners. This is why I have been running 35lbs-R and 37lbs-F for such a long time. Regardless, the OP likely isn't interested much in fine tuning suspension for tracking but thank you for another confirmation of what I had always thought.

After reading a about it, I think this is the best statement, but until today I was convinced that if u lower front pressure you'll decrease understeer:  :confused: :rolleye:

Both are correct. Any deviation from optimum pressure will reduce grip on that end, so going either higher or lower from ideal will work. HOWEVER, if you lower the pressure, you are also softening the spring rate which leads to less understeer and now you have two factors working against each other.

One thing is clear tough, i was wrong.   :surprised:

Hey, I was ready to find I had been wrong all along. I read about understeer corrections awhile ago. I found it helps noticeably having the fronts at 2 psi more pressure and the ride is even softer and easier on the seat meter.

I was convinced that if you lower the pressure a bit on the front, you'll get more grip. I will use this info to my advantage next time I'll go to the track.  :laugh:

I would advise you to use negative camber if you want to race. It's the best option for the track.

Indeed, but too much negative camber is crap on public roads.
