I have seen many pictures of the above cornering hard with one front wheel cocked up in the air, is this a characteristic of cars setup with the more stock lever shocks and leaf springs or do they all do that?
Not too sure about the MBB Sebrings? However, the MGC has a MUCH heavier front end which may conrtibute to the front end lifting up?This was taken on my first trackday in the car (holding everyone up) I almost got it airbourne.
I'm also a mechanical numpty, but have posted a picture of the suspension, so that might help?
See here for a race B V8 cornering hard;

Principles are pretty similar whatever the car, or whetehr it has lever arms or telescopics etc - the stiffer you make the suspension, the less notice/warning you have of approaching the edge where centripetal force overcomes grip in a corner, and the less margin you have to play with in terms of using understeer or oversteer to your advantage. Think 2CV cornering versus an F1 car - with the latter, when it goes, you have no chance of catching it, but with a 2CV, you'll probably scrape the door handles first before anything major goes wrong. The happy balance lies somewhere between the two extremes. Take a standard MGB and drive it; then fit the biggest anti roll bar you can on the front, poly suspension bushes, and change the SAE 20 standard shock oil for EP90 gear oil and feel the difference.....much flatter and less roll, but more demanding to drive quickly without visiting the ARMCO....

Hi DB
Did you make the MGC GTS yourself?
My old man had the work done by MGMotorsport, they did a full restoration.Did you make the MGC GTS yourself?
see the link below, although since then it's had forged internals, roller rockers, rolling road tune up (best part of £8k) and goes a fair bit better than when he picked it up...

Very interesting that..Ta for the link!
I see from your profile you have one....what are your plans?
V8?
Keeping the six? (sounds glorious with triple 45s!)

Mine is a '76 factory V8 that, after a few years of abuse, was in need of attention :-) So I decided on the GTS style.
It's currently at the paintshop.
Started it up a few weeks back...recorded on my phone so quality isn't that good but hopefully you get the idea

It's probably a result of settling the roll stiffness soft at the rear to improve traction and the front hard to maintain some roll control. Lotus Cortinas are a good example of this.niva441 said:
