What is best for Neg Camber?

[Janner_Sy]

nice setup you will have there.  what suspension are you running or is i standard??

my previous setup was coilovers, eibach ARBs and walk and that was very good.  this time though i plan to go for a whiteline rear ARB, walk, TT lower arms, vwr lower mount, and eventually a LSD.  suspension will remain standard for now

I am running H&R springs at the minute, but am changing to bilstein B16s i think at some point. I am planning on a Quaiffe LSD and spoke to matt at VWR but they are in short supply so i am waiting to here from him regarding stock replenishes.

[Janner_Sy]

hows the new setup then, it was bing fitted today asnt it??. would like to know wha camber settings they give you in the end

[geordie56]

Im fitting it all tommorow so ill let you know then. Im then booking it in for a geo alignment at Awesome.

This isn't helping me delay spending on TT wishbones!   

Me neither haha

This is very interesting to see. That the TT control arm has a higher roll center than the stock A3 arm. I have seen that whiteline has roll center kits for Evo and Subaru. That is very nice that this feature is available from a OEM part. I am thinking this part is absolut necessary for any lowered car. The more you lower a car, the lower this roll center is and the more roll a car will have. So if I use the TT arm I can lower my car and it can still handle well. Wunderbar! The problem I have seen in Germany is people like to lower their cars 40-50mm! And they think the car still handles well. But they are wrong, they have more roll and the car understeers because the outside wheel is in positive camber in the turn because the control arm is already past horizontal.

Do you get wider front track when use these arms?

i believe so but not by to much.  you are limited by the length of the drive shafts tbh.  a few guys are looking into scirrocco alloy hubs for the lower rotating mass and wider track

Wow, we can have a real Frankenstein car then with all these different parts!

[vRSAlex]

The thing you have to remember is you also need the hubs from the TT to put the ball joint lower and keep the wishbone as level as possible.  I am currently running the TT wishbones with the standard hubs and the wishbone is pointing up slightly which isnt great for the handling.

The S3/Cupra hubs seem to be different to the TT hubs and they dont lower the ball joint.

I've got PSS16 lowered about 1" from stock wich isn't much at all and the TT-arms gave me -2.3deg wich gave me great results on my last track day at Hungaroring. Problem is, I also switched to semi-slicks so I can't tell how much of the improvement came from the tires and how much from the arms !

If you have your track tires on different wheels, maybe next time bring your street wheels and time some laps with those. I have found it is nice to feel and know what modifications have what effekt. I have usually only modified a small bit at a time on my previous car. Only so can see what the difference was. I have friends who modify so much at once. Car is handling nice but they do not know what part affects what thing. I think it is a lost chance to learn about the suspension and the modification.

What semi-slicks did you have? What were your tire pressure? Have you drive semi-slick tire before?

....I wholeheartedly agree. It's very helpful to feel and so understand what's going on.  

Also, if you happen to get a problem it's easier to find it.

I had the street tires on the previous session but they were GY asymmetric on 235/35/19 . The semislicks are Kumho V70a K90 (hard compound). The only other mod I did was the TT arms wich gave me more cmaber and the time difference was huge : from 2'29" to 2'18" (11 seconds faster) ! The tire pressures were about 2.2-2.3 bar (cold pressures) ! In the first session, they went up to 3.2 bar because over the night there were close to 0 deg celsius and then I warmed them up suddenly. I set them again to 2.2-2.3bar and they didn't go up again in the following sessions more than 2.4bar !...and no, I haven't used semi-slicks before !

So are you saying you tried the new arms with more camber with the Goodyear tires? Then you tried the semislicks? I am just trying to see what sort of time improvements you are having only from the more neg camber. Then see how much time is improved by using the slicks.
