Title: Narrowed irs trailing arms. Who does them?
Post by: baz on June 27, 2016, 17:19:10 pm
I need some 1 inch narrowed A arms and I'm having a hard time finding somewhere to buy them. Anyone got any ideas who in the UK I should talk to?

Hi Baz

Are you referring to moving the bearing carrier inside the arm or another method ?

Jim Wotton at vee-dubs in welling did mine.

Leec is correct about Wayne Allman carrying this out too

Thanks
Darren

Yep moving the bearing carrier inwards. Been trying Wayne but no answer, will try Jim too.

Cheers

I'm still trying to get someone to do mine,  both guys mentioned above are too busy to commit to doing them anytime soon.

Thinking of making a jig and doing them at work with some skilled help.

I have only just clicked back on this thread just now, hadn't seen the last few posts from speedwell.

Thanks dude,  that article is a great help.

Hi Baz
Not many pictures but you probably get the idea from speedwells pictures - https://www.airkewld.com/kb_results.asp?ID=15

There was also an article on Germanlook.net but parts of the site I can't seem to access on my phone - have a look in the tech section.

Thanks
Darren

Hi darren

That jig on airkewled looks easy enough to make,  reckon I could get one made up at work.

The bracket that holds the bearing carrier needs to be adjustable though surely?  Or needs a 25mm spacer to align the carrier in new position?

my jig uses a stock stub axle, i let the carrier slide in on the axle after its cut loose, that way it stays centered

Do you have to narrow the drive shafts too?


Title: Re: Narrowed irs trailing arms. Who does them?
Post by: karl h on October 04, 2016, 10:49:35 am
you have to use narrowed axles or two right side automatic type 3 axles (these are shorter, but hard to find), the stub axles dont have to be modified

Cheers Karl, do you have any idea who supplies these in the UK? that's if you are UK based of course.

custom axles are the only way i think

Nowhere near the UK then  ;D ;D ;D

Pierside seem to list a lot of different lengths:

These are what's needed but at that price plus shipping and customs it's probably best getting custom ones somewhere over here.

I'm on the lookout too but haven't been looking too hard yet, still a ways off needing them yet ;)



Title: Re: Narrowed irs trailing arms. Who does them?
Post by: spoolin70 on October 05, 2016, 06:47:42 am
My bearing housings AND arm mounting points have been moved inwards so I'll be needing some short (probably custom length) shafts.

My first call will be to Pete at Cogbox  ;)

Thanks
Darren

Other side, Karl.  The left one is the short side.  26mm shorter than a Beetle axle.

I know this is an old thread but interested to know whether anyone in UK offers service to move hub inbound an inch for IRS.
Want to get some high offset mags underneath a squareback - thx

Post by: richie on September 08, 2018, 19:51:12 pm
I can do them,I have a jig and done some for couple cars now, got another pair to do next month, max I have moved them is 20mm but don't see why they cant be moved a little more

cheers Richie


Title: Re: Narrowed irs trailing arms. Who does them?
Post by: jmarkha1 on September 08, 2018, 23:53:23 pm
Good to know Richie - thanks.
I will measure up and see where things will end up at 20-25mm
will get back to you...


Title: Re: Narrowed irs trailing arms. Who does them?
Post by: karl h on September 10, 2018, 07:09:10 am
i have found that not all irs arms are the same, with some you can move the carrier in 20mm, with some 25mm or anything inbetween


Title: Re: Narrowed irs trailing arms. Who does them?
Post by: richie on October 12, 2018, 18:48:56 pm
Here's some I am just finishing up that are 20mm narrowed and I tweaked the camber on them so that they are at zero still when stationary even though car is lowered a little ;)

NICE WORK - Realistically how narrow could you go using that technique and retain stock type 3 drums? - 25-30MM?

With custom axles yes looks like 30mm might be possible but until they are cut up its hard to say for sure

That's how I did mine many years ago.  Mine are narrowed 34mm each side.

Beware, your inner ball bearing will not fit.  That's because of the weld on the OD of the bearing housing being right at the bearing. Ideally, you would put the TA on your mill and bore it back to the stock diameter.

Have you checked the clearance between your tire and the tab that bolts to the spring plate?

Bearings fit and yes checked clearance, got plenty :)
