Understeer is the enemy..

[Redev]

Ok so I've had the Golf for about a month now and substituted the Bridgestones for some pilot sport 3's but find that the car still understeers, quite a bit. I'm fact. 

My old TT was fitted with R32 arbs which transformed the car-are there any such revalations for the GTI?

[Nasir]

Check the tyre pressures, they can make a big difference. Also it would depend what you class as unacceptable understeer, every car will understeer at some point.

[stealthwolf]

You can get ARBs for the car which should dial out some of the understeer.

I'm running 36 front and 32 rear...I'm not expecting it to perform like the quattro but I def want to make it a little more confidence inspiring...

[Redev]

Thanks Stealthwolf, any reccomendations on the ARB,s?

[rich83]

Eibach or autotech are the names that always pop up with regards to ARBs

[Redev]

I'll look into the Eibachs..has anyone tried the ARBs from an R32? Just out of curiosity...

Are we talking road or track? Wet or dry?

what tyres, were you hard on the power...

rear ARB, WALK and TT lower arms will kerb understeer without changing the ride comfort at all.  Or you could fit uprated suspension

Assuming you have a gti, I suspect you should first raise your rear tyre pressure to the recommended 35psi

The R32 ARB's are the same has the GTI and Audi S3, 22mm the golf 2.0 GT tdi uses a 24mm ARB at the front.

well, thats the best option to go in war with your enemy

''Understeer'' is a common question.
You'll find many suggestions in this forum (if you may look to).


I'd recommend this:

- high quality coilover like Bilstein B14 or KW V3
- Whiteline ALK for more caster and better traction
- TT arms for more camber
- anti roll bars (to avoid understeer: same diameter front + rear)
- best tyres you can get (e.g. Michelin PSS or Pirelli P Zero)
- same tyre pressure front + rear

The R32 ARB's are the same has the GTI and Audi S3, 22mm the golf 2.0 GT tdi uses a 24mm ARB at the front.

Are you sure?



Some examples:


model / diameter front ( x thickness) / diameter rear (x thickness)


OEM:


A3 Ambition/S-Line: 22,5 x 3,5 / 20,7 x 2,8 both tube

Golf V GTI: 23,6 x 3,5 / 21,7 x 3,0 both tube

Golf V R32: 22,0 solid / 21,7 x 3,0 tube (4-motion)

Golf VI GTI: 23,6 x 3,5 / 21,7 x 3,0 PR-0BF or 21,7 x 3,6 PR-0BM (DCC?) both tube

Golf VI R: 22,0 solid / 21,7 x 3,6 tube (4-motion)

Scirocco R: 23,6 x 3,5 / 21,7 x 3,6 both tube

Touran 170 HP: 23,0 solid / 21,7 x 3,0 tube

Passat R36: 23,6 solid / 21,7 x 3,6 tube (4-motion)

Sharan 2011: 24.0 mm / 20.0 mm both solid



adjustable sport ARBs:


H&R 'regular': 26 / 22 mm both solid

Eibach AntiRoll: 26 / 23 mm both solid

KW clubsport: 26 / 23 mm both solid

H&R 'big boy': 28 / 24 mm  both solid  (heard that there is a 28 mm rear as well on special order)

H&R 4-motion: 25 / 25 mm both solid

Whiteline: 24 / 24 mm  both solid

Neuspeed: 25 / 25 mm  both solid

KW CS are identical to Eibach, just painted yellow instead of dark red.

I think the idea of putting stiffer front roll bars on the front relative to the rear will still give understeer. Wouldn't it be better to go with a more neutral set up like Neuspeed or autotech has gone for? I love Eibach gear but find the ratio of stiffness in roll bars to not help with a understeering car.
