Title: Unstable
Post by: T88OMM on 07 March 2008, 13:20
Has anyone else noticed that ED30's are quite unstable when braking hard at high speed  :undecided: I have noticed it a few times, the car can really snake over the road quite a lot, I have lost a little confidence with it when really gunning it, my last car was much more stable and that was a MKV TDI, I dont quite understand this? Would adding coilovers and arb's solve the problem? The brakes are gonna have to go aswell, I mean they are just ok but after a remap they wont stand up to the job. Would the standard R32 brakes be better as I have a full set in the garage??  :sad:

Dont have an ED30 but my GTI never does that. It stops in a straight line even when i slam on the brakes from 60mph+

I've hauled my car down from some pretty hairy speeds and its straight and solid all the time. This may seem condescending (its not meant to be) so feel free to virtually slap me, but are you braking in a straight line. If you brake hard and move the steering wheel or brake in a turn, even a slight one, you will shift the weight of the car around the axles which will give you the snakey feeling.

Advanced driving courses  teach you how to manipulate weight transfer to your advantage and a feel for the movement of the car.

Of course it could just be a sh!t road  :grin:

My ED30 doesn't have any issues like this. Retardation is straight and true. :smiley:

Maybe try and slow down and not drive like a man possessed might help???? where would be able to do that manouver without driving too fast in the 1st place???  :rolleyes:

I've got a standard GTi and that's one of the first things I noticed after getting it. I wouldn't say it snakes all over the place but it does sometime squirm a fair bit when braking hard from high speed. It is better after fitting pilot sport ps2's on it. The BMW I had before was much more sure footed and felt rock solid. I guess it may have something to do with the weight & distribution, slightly stiffer suspension and having 255 tyres on the back.

Maybe I exaggerated a little with the snaking all over the road but it is not quite as stable as my previous cars. i meant the car moves around when braking through corners  :sad:

The R32 brakes are immense, but it does sound like there may be some other problem, which the huge R' discs may just accentuate.

braking round corners = your ESP trying to stop your car oversteering perhaps?

when braking through corners  :sad:

This may be the route of your problem. You should brake before the corner, consistant power through and then accelerate out of it. Braking mid corner is very good at upsetting the balance of any car.

I agree but in real world situations traffic etc. the brakes have to be applied round corners, long motorway bends etc, stopping from speed due to some idiot pulling out etc. Having raced go-karts for a few years I understand the methods used out on the racetrack but as we know the roads are not race tracks  :smiley:

Fair point, you weren't too clear on the circumstances in your first post under which these problems where occuring.

It culd be down to simple tram lining due to the wide wheels on the GTi. I would say get your dealer to check the tracking as that may be an issue.

sorry cant be @rsed to read the whole thread but i know what you mean tom, i have the same problem but i think you may be exajurating a little? when breaking very very very hard from speed of 70-80 then slight snake like movment is present in my car aswell. dont think its much to worry about  :smiley:

Post by: Manu_R32 on 07 March 2008, 15:29
I sorta feel this aswell but it very well could be the ABS kicking in or something....which allows the car to shake/wobble....especially if ur going quite fast and apply the brakes quite hard?

Yeah I don't think I have explained very well  :embarassed: I mean braking hard round a corner due to an obstacle. It just did not feel as stable as previous cars  :smiley:
