When I first brought mine home on it's 1,000 mile journey the springs had sagged to a point where I would bottom out on the catalytic converter cage on every speed bump regardless how slow I took it. I drove it very carefully as the objective was to make it home without incdident. It had been stored for 7 years and most rubber was shot.

I replaced front rubber with poly, new KYB front shocks, standard springs, ball joints and tie rods. I haven't touched the back suspension. The handling is tight and seems eager to take on the tightest corner. The only negative is it got twichey when I violently sawed at the steering wheel to go through an obstuction on the highway (about 55 to 60 mph.) I put that down to worn front lower links which I didn't notice until I had new ball joints put in but used them anyways.

I wouldn't want heavier springs they seem heavy enough as it is. I'm not going to rally this car. There is no noticable dive so I won't need the anti-dive kit. I always thought it would sit pretty low and worried about getting into jclay's situation. The poly seems to transmit all the road information I need. The TR8 steering wheel (standard on the Spider) seems small on the non assisted rack, like I'm driving a go-kart.

The point I'm making is the standard suspension with new parts and poly seems great enough to me and unless I'm going to take it to the track anything more would be a bit much and over the top. IMHO.

Wow - two post hoist in the garage - that must be very handy!
Are these aluminium 'solid' subframe mounts in the top picture?

A friends workshop, indeed very nice and very well equipped.

Subframe mount indeed are solid alloy. More or less home made [:D]

Hmmm, interesting stuff Beans.

Do the solid sub frame mounts make it a bit harsh?

Like the strut conversion you've done.

Looking in the photo, have you also modified the lower track control arms to make them adjustable?

Thanks to all for the photo's

Now that I have fitted an anti dive kit, it is the lowest part of my car. I ran the car into a parking lot concrete stop really hard on the right hand side bolts holding on the kit, didn't see it.

Now I have noticed that the steering wheel is off center to the right and sometimes the car will pull in that direction. Also, it will some times seem like the steering is floating at speed. I know that the steering is tight. It is like the toe-in is off and the car doesn't know which wheel to track on.

The bolts don't seem to be bent, but could I have shifted the x-member back on the right hand side and messed up the tracking? Has anyone ever had this problem?

Have fun, drive fast & safe, be kewl,

Jclay, as you know, you would have had to hit the thing very hard,
enough to deform the subframe, or the chassis rails, to have moved
the suspension back, permanently.

However, depending on what material, & how old your bushes are, they
could have been deformed, allowing some movement in the subframe.
This would give you variable caster, & toe in, & vague steering.
The same thing could have happened to the rear anti roll bar bush,
with a similar result.

I presume you have checked the subframe is not damaged at the roll
bar mounting point.

The symptoms you describe suggest to me that you have altered the
toe in, which makes the car steer first to one wheel, then the other.

If there is no deformation of the chassis rail at the subframe bolt,
[seen from the top] I suggest a check of the sway bar to lower
control arm bushes, the sub frame bushes, & check of the toe in.

No, it only makes the handling a bit sharper.

Those indeed are adjustable TCA's. Got them from Demon Tweeks in the time that they still stocked TR7 goodies. Came with spherical (inside) rod ends.
As a result of all the mods carried out over the last 10 years the car ('t Kreng) handles very well. Much sharper and more precise then the DHC which also stands on uprated suspension.
