Wheel spin followed by a bang?

[Martin]

Higher spring rates is usually the solution. For FWD more caster/anti-lift helps too.

I now have the VWR springs and the supaloy control arms which have more caster
These seem to have eliminated the axle tramp (more aggressive testing pending)

[Martin]

I have now tried launch control and deliberately used too much throttle trying to promote axle tramp
With the supaloy control arms there is no axle tramp at all
The wheels just smoothly spin, traction control kicks in, grip re-established smoothly without any bang

I'm rather pleased with this outcome...

I've got the supaloys and when I rev over 2-2500 all it does is either false neutral or burn rubber


ps. Martin I'm uber keen to hear your APR exhaust ... does it gurgle??

So just for clarification, the supaloy control arms significantly reduce axle tramp and improve traction?

[Martin]

Interesting - I did get a false neutral once and was perplexed by it

On the outside it does have a faint burble
On the inside the idle is a little louder but nothing cool or interesting
The gas noises at wide open throttle are strange and add to the sensation of speed
It's only the downpipe from the turbo to middle of the car - from there backwards it's stock
(The down pipe does have a high flow catalyst)

Hey Martin,

where did you get these springs supplied and fitted?

Thanks

[Martin]

I got the work done at BWA Auto's in Seven hills - APR Agent
They are porche/VW focused shop - lot's of history and experience
They don't get to see most of their customers, the cars arrive on a truck
First time I went there there was a old Octavia having the brakes worked on - all four corners
And while I was there, three trucks turned up with Porche's to be worked on (2 street machines and 1 racer)

If you have the time and a few tools you can eibach springs from UK (direct or via ebay)
and fit them yourself and save a lot of money (VMR stuff is expensive)
I was having a lot of work done so I got them to do it all

I will also say that I am now used to the firmer ride (initially it shocked me)
It's just below the comfort level I prefer but feels great when you push it
Have to be careful coming out of driveways - the tow bar smashes the ground more often now

I would put a higher priority on the supaloy control arms - thay have made a significant improvement

The supaloy control arms totally eliminate axle tramp but I would not say they improve traction
If you give it too much on launch the wheels will easily and freely spin - need more throttle control and restraint
The initial turn in is more precise and quicker (some improved feel until the power steering kicks in)
The high speed (+180kmph) stability is also improved

[Tigger]

The high speed (+180kmph) stability is also improved

In theory only, of course....

Absolutely - that's just what was written on the packaging
