Hello fellow Pred-maniacs.
I just found the latest Worksop-article.
Seems Nathan showed some nice driving in 2WD. But, Nathan, no TQ in 4WD too? Pitty ;)
I also noticed these photos about new parts/ideas
Could someone gove some more info on them?

this one is obvious, jsut some sronger rocker posts.
I really apreciate these, ... since I broke my first rocker (hollow one) post this weekend :)

new position on the pushrods.
I made already such a modification on my X11 with some regular bolts and nuts.
The use of the new Aluminium Servo posts seems much more convenient ... but on any way you want to make this mod .. the exact location where to drill and mount the servo-post is important for a fine functioning.
I can imagine that some new Front low A-arms will be produced with these holes provided, but in the mean while, I still have enough "regular" ones.
Could someone provide some info, pictures, measurements on how and where drill the A-arms.

Also a litle tip. I previously used the 30mm-turnbuckles (rear toe-adjustment) but I found these to be a litle too short.
I then found some old 3mm Tamiya-turnbucles (35mm and some 38mm ones) which are just the perfect lenght.
RC 3x35mm Titan Turnbuckle (http://www.tamiyausa.com/product/item.php?product-id=53528) Item #53528
RC 3x38mm Turnbuckle: 93013 (http://www.tamiyausa.com/product/item.php?product-id=2520016) Item #2520016
RC 3x38mm Blue Titanium - Turnbuckle Shaft (2 pcs) (http://www.tamiyausa.com/product/item.php?product-id=42119) Item #42119 (blue titanium = could be expensive!)

Rear Hub extensions
wow, what's the idea behind this? To extend the rear wheelbase? But then Jimmy wrote the suspension arms were shortened...


all extra info would be much apreciated :D :p

The rear hub parts are prototypes - I assume this would involve both new rear arms and new hubs as production parts. This keeps the same overall width but moves the pivot inboard which is supposed to aid rear traction / stop it breaking away under power.
I've not tried it yet but hopefully soon :thumbsup:

I did have the front end 'team mod' on my car, but after smacking into a bench at Worksop and replacing suspension arms, I didn't want to keep drilling the hole for the new pickup point. So I've reverted to standard kit suspension setup at the front and still thought it was great at Batley last weekend - very pleased with how it went.

@ lowie

i have put 2 new holes in the front wishbones, for have 3 different position to mount the turnbuckles of the pushrod, 1 the original hole, and 2 new holes.

yes, but the drilling positions are quite critical.
If not positioned right, the pushrod might touch the axle or the steering-turnbuckle.

That's why it would be handy to have some measurements.
I drilled a hole right in the middle between axle and steering-shaft, ... but I can't use that same hole when I want to mount the alu servo post, as the ball link will touch the steering link.
It seems to me, when using the alu servo mount, that it can be positioned under the axle ...
but I do'nt think it's wise to drill different holes close to one another, .. so I'll have to use a new suspension arm.

I have some pictures somehwere, showing where I drilled my holes, i'll post them later (on work now)

[edit] here they are:

i will get kevs and my measurement as we both run in a different hole to get different characteristics from the car.

for the positions of the servo mount...i have tried in this solutions:
mount on servo the ball, put the centre of the ball in aligment of the centre on the holes of the original wishbones...
