Tramlining & Excessive Torque Steer.

[kaanage]

Spoke to the Guys at Pedders (pedders you say), tho it was a while ago. The guys at South Melbourne are great and really into performance cars, workshop is always full of great machines.

Anyway I was telling him about them, and I was told how they use the slack in the subframe to make small adjustments if they need to when doing a allignment, and without small adjustments well makes the car harder to setup?

Is this correct

So these guys know about shifting the subframe. Does anyone know of anywhere else in Melbourne to get an alignment that includes this? I just spoke to a place and they talked about taking the car to a panel beaters for adjustment on a jig.

BTW, I don't know if it was Eddy's subframe sleeves, the Whiteline front anti-roll bar or the camber plates/strut lengthening but my power transition clunk is totally gone (there are some new noises but camber plates, hey ) and the steering feel with my lower offset track rims is almost as good as with the stock rims

Can't wait to hit the track on Cup day.

Hoyhoy.

Greg, with using the hex head on the sleeves it will move without any jigs, plus how can ya align on a panel beaters jig.
Just keep moving the sleeves one or two @ a time until happy, it can take awhile.
I marked where all the sleeves ended in each housing with a punch 1 to 4 (thats sleeve & housing), now its easy to pull the sub frame out & back in without a wheel alignment, except for toe.

Yeah, I know - it was just the excuse from the wheel aligner not wanting to have to do more than fiddle with tie rod ends

That's why I'm trying to find someone who's serious about alignment.

Any of these suckers left Eddy??

[Eddy]

Hoyhoy.

Fair call Greg.

[Eddy]

Any of these suckers left Eddy??

Hoyhoy.
I don't have any kits left, sorry.

[kaanage]

Sorry Sam - I nabbed the last set.

[Eddy]

Hoyhoy.

Bulk buy might give me some inclination to do more.

[noone]

I would love to Eddy, just don't have the know how to do myself and my mechanic isn't up for this sort of Engineering.

If I do make contact with someone decent, it will be on my list.

Any new lap phenomena's for us?

[Eddy]

Any new lap phenomena's for us?

Hoyhoy.

No new lap times, not even bad ones.
Will be back @ Waky on 29/11/12 (Speed off the Sreets with no offical timing) & then on the 1/12/12 with Circuit Club, (offical timing).
Don't expect to improve times, but will be trying.
Will be logging intake temps for peace of mind.

Eddy did you ever make any bump steer geometry improvements?

Eddy did you ever make any bump steer geometry improvements?

Hoyhoy.

No, all I done was lift the front up a bit.
I have bigger bump steer problems than any one else because the clutch diff shows it up more.
Last October when going down to Waky towing a trailer, I accelerated hard overtaking a truck on very uneven surface, the effect pissed me off.
Mind you that on the track & even rough surfaces it's great to drive.
Since then I done a series of GoPro vids underneath the Little Blue Girl, finding some interesting things going on.
The rear Seat bush even after years of use held up superbly.
Then the fronts surprised me, Fulcrum made me a special set in 95 duro which is the same material as Superpro but a bit harder, they came out looking brand new.



But the videos showed that they could flex too much for my liking.
After researching & talking around I got a set of bushes made with a product called Acetal.



Test run gave great improvement as to bump steer concerns.
Time will tell as to how they go.

I've made myself a set of these "Sub-frame hanger bolt cam sleeves" - I'm very happy with the change

I'm happy to make a set for anyone who wants them, no need for a group buy. Similar money to the bloke who made them for Eddy

[sambb]

Did yours require the subframe to be reamed for them to fit Simon or were they a snug direct fit?

direct fit Sam - I sized it to slot into the subframe
