Would I be correct in thinking the higher the 'slip' angle (not sure that is the right term) the more sideways you are the more the mounts will flex and the more you will be turned into the corner?

The mounts will only allow so much movement as they are'nt designed to give much, but the harder you turn (up to a point) the more rear steer you will get.

Exactly, they help you passively steer the rear through a bend. So the more steering effort you put in, the more force that is applied to the mounts and as Daveyboy says to a point the more assistance to steering they will give you.

The reason I am not a fan is because if you turn in hard and then find you need to lift off you will incur the famous LOOS and that has caught so many people out over the years. With the solids I find that more effort is required for a hard turn but the rear stays where you think it should stay and is more managable. Wink

That ALMOST suggests that by only changing the rear mounts and not touching the front, you'll have a little more understeer or a slower turning car?

I've been caught out by LOOS at high speed and at a not so high speed, though both instances were in the wet.

I've only once experienced it once in the dry with some very hard turn in, luckily, I caught it, but it was still a little disconcerting

This is true, and in order to give you back the feeling at the front, front end mods are then needed.

To be fair, I upgraded the front and got it pretty much where I wanted it before I messed with the rear...Yes

Then once I had the rear sorted, I then fettled with the front and got the whole setup to where I felt really happy with it.

I can't quite imagine many people would leave the suspension completely standard and only upgrade the rear mounts to solids.

My plans are only for 25mm front springs on b4s. It already has new genuine rear mounts.

I'll be making and fitting some solid wishbone bushes too

Sounds like you've got the front end pretty much sorted then. I started off with Spax and ran that 40mm drop for about 3 years I think, subsequently moved on to KW V2's and really like them. Smile

Do you think solid bushes and b4s on eibach springs would be stiff enough to balance the back with the hybrid arb

I would have thought so, sounds like a decent setup. Have you thought about going for a 30mm ARB?

I ran that spec for a long time. As long as the car isn't lowered too much it is a great setup Yes

As long as you ask for OE/lemforder from GSF you will get exactly the same mounts as you will get from Peugeot at a fraction of the price.

The larger mount came in a box marked 'Hutchinson' or similar.

For a nice fast road setup, I would suggest the 30mm ARB with solid beam mounts and 21mm TB's. This is what I run and the rear end is planted. Smile

I wish I could afford it!!

I'm putting eibachs on my b4s and renewing the front bushes. Hopefully it'll offer a little more front end confidence

I found uprating the rear end on my car/s affected front turn in dramatically.

Yes I agree. The setup I posted above which I currently run made the front end very 'pointy'. The steering wheel feedback was great and the car just went wherever you asked it to go.

The fact that I've also got R888's all-round as well just compliment the setup totally and make for a very solid package. Yes

Right, well Smile....

I've got new top mount bearings, B4's and Eibachs.

Will be matching these with solid front mounts and probably powerflex comp rears (I don't have time at present to machine the rears).

Hopefully, that'll give a bit more balance.

At present the rear feels like it squats down nice and tight and the front "floats/wanders" around
