Thread: Lifted P38 on air - questions

I see your blue shed toys are the same as mine!

Thanks so much for that!
Yes, I would say that at full bumpstop compression they are just touching. So no spacers... I think I'm going to end up with a 1/2 inch alloy plate bolted onto the bump pad of the chassis - in which I'll loose a tad compression but I don't see any other way.

Yesterday whilst I had no rear springs in, I jacked up one tire to take all the rear weight of the car on one bumpstop to try and simulate a bump, the bumpstop didn't compress any further. I had 22mm from the bottom of the retaining cup to the bump pad on the axle.

Yeah, it keeps the daughter out of my tools! She loves helping work on daddy's car! She is only 18mnths old but can tell the difference between a screwdriver and hammer!

22mm from the cup to pad sounds about right to me, I didn't measure it but called it an inch with my good eye.

Thats so cool. Both of our kids love helping in the shed too; though the youngest one was banned today as it was up on stands - who knew a 12 month old could get so angry. .. not upset, actually angry - we started calling him James because he turned red.

So the overall problem with the gen3/TF145 with no spacers is that it over extends the bags by 1/4 of an inch. The extra 2 inches at the shock give 2.36 inches (6cm) at the bag, and with the added rotation of the diff it pulls the bags out to 18 inches; to which 17.75 is the maximum arnott specify.
It pulls them pretty tight too, you can't see it in the photo but it was lifting the rear of the piston off the diff (had the pins in obviously but it was lifting a whisker or so)
This was with 50psi.

So... If I lift the back of the bottom piston by 1/4 inch (which by the look of it would make a big difference), or, I could cut 1/4 inch off the upper bottom shocker rubber...

I'd be inclined to lift the rear of the spring by 1/4" over messing with shock rubbers! Makes the most of the shocks that way.

This is the photo at 50psi I wad supposed to load up.
Now to find a way to lift it 1/4 inch. May have to bite the bullet and drill and tap the piston to bolt it down with a sandwich plate.

It's quite amusing reading about the younger kids antics. Mine are all grown up now, but still a source of amazement. Yesterday I was asked if he could borrow the boat to go fishing. Yes, no problem I replied. Then it was followed by "oh, and I'll have to borrow the Rangie too because my car can't tow the boat". Gotta love 'em

I've gotta ask, those three lines coming down onto your diff, what are they! I don't believe I have them on my '99...

If you make the angle spacer thingy, you will probably get away with cutting a boss in the plate and using factory pins. My bags are held to the spacers that way. Then just weld the spacer/plate to the diff. Again, my rear spacers are welded to the diff.

That looks like the way to go.

Early GEMS had the brake hoses jump down in the middle of the diff, along with the abs leads.

Cool, thats great, thanks.
