I have recently bought MGB GT V serial number 2520, about 70 cars before the last factory built V8.

I intend to upgrade the suspension am would be grateful for opinions on any telescopic damper kits for the standard front suspension. In particular, i have bad steering wobble at around 75 to 85 mph., and I want to be sure that this can be cured by renewing the bearings and bushes in the standard suspension and adding telecopic shockers.

Eddie, the shocks are not your problem. If they do not leak and have oil at the proper level there is no need to replace them. It is much more likely that your king pin bushings are worn. Put a jack under the lower control arm and lift the tire off the ground then see if you can wobble the wheel top to bottom. Then have a look at your tie rod ends while wobbling side to side, and finally pull the grease cap and look at the spindle nut to see if you have any play there.

Welcome to BritishV8, and congratulations on your new car!

I agree with Jim that telescoping shocks are unlikely to fix your steering wobble problem...

Jim's already done a good job of pointing out most likely problem areas, but there is one other thing I'd add. When you take the suspension apart to change the lower control arm bushes, have a good look at the inner pivots ("fulcrum pins") on both sides. (That's number 64 in this drawing: http://www.britishv8.org/Articles/Images-V17-1/MGBGTV8-Parts-Catalog-H1.jpg)  I found that my car came with bent pivots on both sides - apparently the previous owner had hit some potholes very hard or slid into a curb.

Knee-action shocks are durable and rebuildable - and they have at least one theoretical technical advantage: they don't contribute an ounce to "unsprung weight".

You can spend a great deal of time and money restoring, modifying, or rebuilding a tired MGB IFS. I did, and in the end,  was still stuck with old technology.  I have no idea if most MGB drivers are satisfied with the MGB IFS design, or if they consider radical modifications to be it a negative step.  I know the MGB V8 guys don't fit that mold. So If you are open to the idea of non-original components, you may be interested in the IFS made by Ted Lathrop at Fast Cars, Inc.

I've attached a photo,I hope you can see it okay.

I've driven several MGBs with the FastCar front crossmember...and we recently installed on on my MGB/GT V8 project.

Additionally, we installed a Classic Conversions four-link rear suspension.

I am anticipating good things...

Hi Eddie,
I experienced the same thing with my B.  The front end was tight ( rebuilt ) and the shocks were OK with fresh fluid.  I  suspect it had to do with the spacers that I installed to mount Corvette wheels on the front.  Over Christmas I installed an 86 Vette front suspension on it and I expect it to make a tremendous difference.   As soon as I can get home and start the fresh engine and take it for a spin I'll post how it goes.  The Jag rear really makes a difference in the ride.

Bill, Great car! Great job! What model Jaguar rear end did you use?  Would love to see photos of the IFS too.
