very light on the front while driving
I have had my MGF 1.8 for just over a year. I have never driven one before this and have been experiencing a unstable feeling while driving over 60mph. The tyres are new and the balancing is correct, is there a particular reason why the car should feel much lighter on the front wheels than the back, or is that just all rear while drive cars? It really does feel as tough I need a concrete block under the bonnet.
Kind Regards

Re: very light on the front while driving
In my opinion, from personal experience of my F when I first got it, you are thinking the same as I did. If you look at the front of the F you will see the curved underside of the front bumper, in my opinion the wind gets under there and at speeds above 60mph, (I felt 55) it's actually lifting slightly giving you the feel just as you describe of light vague steering.
I fitted a KH splitter (you could also fit a "Trophy" spoiler) these will improve the aerodynamics and push the front end down and give you a more positive feel.
Just my opinion but it worked for me, you don't need one on a TF as it has a small lip spoiler as standard that does a good job up to maximum speed.

Re: very light on the front while driving
Choice of tyres has been mentioned as a source of odd feeling handling as well. What did you fit when you changed? I agree withthe TF at speed BTW, joy to drive. The spoiler is a win win as less lift means less drag.
Re: very light on the front while driving
Late post I know, but I thought exactly the same re the lightness of the front. The advice to fit a splitter is correct in my opinion, KH one about to be fitted on mine.
If you have EPAS, as I have on mine this tends to exacerbate the waywardness of the front-end - so I suppose all is normal, although I was suprised at it's sensitivity when compared to my Y2K Ford Focus.
Also agree about the sensitivity to tyre types/makes, well documented elsewhere. Preferable to use tyres with very stiff sidewalls.

Re: very light on the front while driving
Piers,
Agree that the addition of a front splitter will solve the problem of the front feeling light. Our F felt very light at motorway speeds, but was totally transformed when the front splitter was fitted. Whereabouts in Somerset & Dorset are you? If you're local then I'll gladly take you out in our F so you can experience the difference.

Re: very light on the front while driving
Are you guys still carrying the spare in the front?
Does it help?
Does a EPAS switch help?

Re: very light on the front while driving
Yes, I have the steel spare in the front ~ it's always been there.

Re: very light on the front while driving
Would try the tracking perosnally, as would guess the front are set well toe out, or incorrect at least. Also the lower the profile, the lighter it feels for me (215 40 16 on mine)

Re: very light on the front while driving
Yes I had the very same prob when I first bought my F and very scarey it was too.
I brought it to the " MGF Centre " and they fixed it by setting the traking. They gave me a copy of the settings for future referene which i will hoke out ( hopefully ! ), scan and send them to you whenever I get home maybe later this week or early next week.Just let me know if you want them i will be happy to do it for you.It really made a huge differene as the car now sits on the road and handles as a sports car should
Hope it helps you

Re: very light on the front while driving
It is a combination of things:
- Aerodynamic front end lift (well documented - some more summary here). Fitting a KH splitter helps no end with standard suspension settings - and is a doddle to do (more here)
- Tyre choice/ mismatched tyre brands front to rear/ tyre pressures - fit a recommended tyre, and ensure that the tyre pressures are correct (I personally find 30psi all round works well, but that isn't the standard setting)
- Tracking - the standard figure for toe at the front is 0deg10min toe out. Toe out at the front is said to improve turn in response, but also increases instability. Going for 0deg5min toe in per wheel really makes a substantial difference to steering feel and stability. More here.
On my car, that's been lowered on knuckles and tightended up on Bilstein dampers from Tech-Speed, there's neglible difference from the fitment of the splitter - so I've not had it re-fitted since I replaced the front bumper.
Regarding EPAS - yes, it's pretty easy to fit a cut-out switch, but although there is a little more steering texture at speed, it doesn't cure the problem.
BTW fitting a TF steering rack is not only quicker than the standard MGF EPAS rack, but is also more accurate and results less wander on the motorway.
So there's a summary of some of the contributory factors (and I've not included worn suspension components as a cause - but clearly worn bushes and track rod ends/ ball joints will all have adverse effects). I wouldn't necessary rush out and follow all the recommendations at once. I'd probably check the suspension components for good health, check the tyres, re-set the tracking and consider a splitter.
If you're planning to head track-side, then up-rating the suspension and considering a change to the steering rack and a few of the other more extreme modifications will start to to make sense.
Hope this helps!

Re: very light on the front while driving
Got to agree with Rob. Fitting a splitter to a standard car doesn't cure the problem, it just masks it. My car is lowered with adjustable shockers and "Toe In" settings and it's as solid as a rock at high speeds. I've a splitter fitted but only because someone gave it to me for nothing. It didn't make the slightest difference to how my car handled.
