I was thinking of that too, and i suggested to iain about Tigra ones as there plated but not as strong as aftermarket plated ones :)

Just need to get iain some pics.... when i remember lol

I've seen tigra/corsa ones and didn't think about coping them. Plate them but with a gap in the middle...

Iirc tigra/corsa ones are to long...

lol, project looks immense, i have sent you a pm about your engine :)

They ARE the same lengh. I have a ****ing tigra and i compared the lenghs!

Bear in mind its not easy. But you can see there not 1 inch longer at all. You can also see the strengh plate.

^^ you idiot - there obviously longer even from that angle

That pic isnt the best, but the one held up is the nova one, There the same funking lengh!

aw06 they are the same length. i run corsa bottom arms on my nova. its the chassis width of the corsa that is wider not the running gear.

Excatly.

Was gonna saying going by that pic its just the shape that difference..

Got my eccentric topmounts back after being machined down for slightly more camber/caster adjustment, thanks to Nova Ian.

Also stripped down my steering rack for the Quaife internals:

Poly rack mounts to be reused:

http://iainel.co.uk/images/forums/NovaWIP2/621.JPG

All of it was quite easy, just unbolts. Found the best way to get the pinion out is a pair of mole grips and hammer it up and out:

http://iainel.co.uk/images/forums/NovaWIP2/622.JPG

Out!

Rack casing to fit my internals in to:

Ah have wonderd how you take the rack apart...

It's dead easy, just remove the arms, undo the big tension nut, and the pinion comes out after removing a circlip.

You got the bearing back in then! lol

Did you finish painting that fuel tank??!!

Good stuff Iain

Yeah got the bearing back in, I modified the circlips too so they weren't touching the bearing when they rotated. (Remember what I was pointing out to you when I first gave them to you)

Nah fuel tank is half paint strippered, that's one for a rainy day in the garage! lol

have you got a pic of the top mount before the work was carried out? how much did nova ian charge if you dont mind me asking?

bruce

Here's the topmounts before fettling. I think it's about 3mm taken off. It's Ian's mate that did it so PM him for more info!

http://iainel.co.uk/images/forums/NovaWIP/131.JPG

They the rally design ones? Look similar but mine don't have the recesses either side of the bearing, that i've noticed anyway.

They're Compbrake CMB0230 topmounts.

A little more work on the rack and topmounts today, pics are more for reference than an interesting update!

Quaife internals vs standard:

http://iainel.co.uk/images/forums/NovaWIP2/625.JPG

Part no. on pinion, also the bearing I need to fit to my new internals in the bottom left:

http://iainel.co.uk/images/forums/NovaWIP2/626.JPG

Looking at the bearing number, and comparing it to Olly's post, it's a standard one. So I've ordered a new one:

http://iainel.co.uk/images/forums/NovaWIP2/627.JPG

Measurements are 40mm outer diameter, 17mm internal diameter and 12mm thickness:

http://iainel.co.uk/images/forums/NovaWIP2/628.JPG

Next, on to the topmounts. I had bought new threaded inserts to use but they're too long, over 3cm here:

http://iainel.co.uk/images/forums/NovaWIP2/629.JPG

Which leads to this:

http://iainel.co.uk/images/forums/NovaWIP2/630.JPG

So I dug out my old ones which were already cut down:

http://iainel.co.uk/images/forums/NovaWIP2/631.JPG

Much better:

http://iainel.co.uk/images/forums/NovaWIP2/632.JPG

Perfect:

Not sure if I've said yet, but I'm upgrading my 275lb 8" springs (for the 16SE) to 325lb 7" springs for the 20XE:

Next up I had a play with my camber bolts!

http://iainel.co.uk/images/forums/NovaWIP2/636.JPG

Fit in the strut like this:

http://iainel.co.uk/images/forums/NovaWIP2/637.JPG

http://iainel.co.uk/images/forums/NovaWIP2/638.JPG

However two problems....

1 - I cannot get full adjustment as the washer hits the strut here:

http://iainel.co.uk/images/forums/NovaWIP2/639.JPG

And 2 - The bolt can twist without moving the washer?! So that surely makes them unsettable as the washer can be pointing in a completely different location to the bolt!

Have you still not got way too much thread sticking out the top mount??????

And why camber bolts? Just adjust the top mounts :confused:

I though this when i had my LEDA's, but when i fitted it all upto the shell, i ended up with umpteen more adjsutability.

There's loads of thread coming out of the topmount still because I have the topmount straight on top of the top spring platform:

http://iainel.co.uk/images/forums/NovaWIP2/640.JPG

The coilovers are designed for standard topmounts. Most people fit the bottom and top spacer which leaves a 'normal' amount of thread poking out the top, but the benefits of what I've done are no play in the top spring platform, and slightly more travel at lower ride heights.

Camber bolts.... Just more adjustment. I can set the topmounts for maximum caster and sort the camber on the bolts - win win!

Them bolts are more for caster then anything, but as Ad say's the top mounts give more then enough adjustment Iain.

Good progress though mate.

Scott

I can't see how the bolts modify caster?

I used to run -1deg neg camber and +1deg caster on the topmounts, so if I can set the topmounts to give more caster then the bolts alone will get -1deg camber.

That's the theory anyway, if I can iron out the weird issues explained above then I'll use 'em.

concidering they are called camber bolts then im guessing scott is abit sleepy

Luke it quite clearly Say's on the box camber/or Caster.

Depends what the setup is on the car. Novas, and infact most vauxhalls it will adjust the camber.

Okay my confusion about the bolts is no more. Instruction video on the bolts here helps: http://www.youtube.com/watch?v=O4Rf0szJEj4 I thought the tabbed washer was supposed to be turned to adjust the camber, but you actually adjust the bolt head, doh!

Here's some pics of how they affect the hub-to-strut angle for those interested in the bolts.

Tab outwards for positive camber:

http://iainel.co.uk/images/forums/NovaWIP2/641.JPG

Tab inwards for negative camber (well, as inwards as I can set it without hitting that lump on the shock). See how the bolt head is sitting much further inwards now?

http://iainel.co.uk/images/forums/NovaWIP2/642.JPG

Here is the angle of the hub to the strut when it is full positive camber:

http://iainel.co.uk/images/forums/NovaWIP2/643.JPG

And at full negative camber, you can clearly see the top of the hub is angled further in to the strut:

http://iainel.co.uk/images/forums/NovaWIP2/644.JPG

I believe my Leda coilovers have these on the front, i think i should investigate, as one of my wheels (cant remember the side) is slightly more on the piss then they other.

Looks like the work quite well.

where did you get the bolts from buddy ??? :thumb:

They're from LMF Vauxhall: http://www.lmfvauxhall.co.uk/

cheers buddy

Topmounts were looking a bit sorry for themselves so they're now bling and polished lol Before on right, during on left:

http://iainel.co.uk/images/forums/NovaWIP2/645.JPG

Done:

http://iainel.co.uk/images/forums/NovaWIP2/646.JPG

Wire brushed and sanded down the front coilover:

http://iainel.co.uk/images/forums/NovaWIP2/647.JPG

A few coats of Hammerite black smooth and they look nice:

http://iainel.co.uk/images/forums/NovaWIP2/648.JPG

Rears were in a similar state. They have rusted, but most of the brown you see is copper grease (I thought it would be a good idea to spray this over the threads, but it just seemed to catch muck and make them go manky!

http://iainel.co.uk/images/forums/NovaWIP2/649.JPG

So these were stripped down and sanded back also:

http://iainel.co.uk/images/forums/NovaWIP2/650.JPG

Having trouble getting paint to stay on these, seems to flake/scratch off easily. Must be something to do with them being zinc plated from the factory. Is there a special zinc-plated metal primer I can use?

Christ tops mounts have come up great, really good job.

Using a etch primer should help the paint stick.
