Well I was told by someone in the know to leave the front alone, but stiffen the rear to dial out understeer.
I also fitted uprated bushed, solid droplinks and an ALK.
Mine now goes like it's on rails............but Britain's 3rd world roads play hell up with my fillings

This is what the general consensis is with the anti roll bars. If you want to do them both then go for 20mm front and 24mm or larger on the rear. I would go for 24mm rear.
The other good thing with the adjustable ones is that you can dial in how much oversteer you want depending on what setting you have it at.

I fitted a 22mm rear and left the front alone which totally transformed the car's handling, giving a nice balance
Here's what I said in a past thread after fitted the 22 rear:
Quick note on the rear Whiteline 24mm arb recently fitted on my 96 Sti.
Car feels totally sorted now.
Handling has gone from soft in the corners with rear wallow and a feeling of quite a bit of overall roll, to feeling tighter, flatter, more precise on the steering, with a huge increase in the amount of overall grip. I would say the car's balance is neutral. The arb is on the middle setting.
Handles like a true Scooby now
I reckon the rear arb has got to be must upgrade. On a bang for buck basis you get a massive improvement for your money. Highly recommended...

Hi I have a bug sti, i had a 24mm rear fitted, alk and droplinks, this was very very good, i then had a 22mm fornt bar fitted, threw the old one away, and even on the soft setting its horrible, wish I bought something else instead, so im now looking for a standard fornt bar. I dont think you shoukd bother with the front.

Bugs (and all newage) are diffrent though - much heavier than a classic and therefore isn't there more weight for the ARBs to deal with? therefore they will work differently with the 22mm front and 24mm rear set up.

Rear 24mm Whiteline for me, with Anti Lift kit and upgraded drop links and Tein coilovers. Car is planted to the ground with no understeer at all, turn in as sharp as you like and car just goes where you point it.

Hi m8, The car does not take bumps very well at all, seems to follow the road rather than the input I give from the steering (if that makes sense), the steering feels very vague now, just doesnt turn aswell as it used to, the tyres (toyo proxes t1r) seem as though they are squirming under the car, very crashy, bangy ride. I read threads on here about lift off oversteer etc, got worried and had the front fitted, the car did not oversteer in the slightest, even in the wet, had the front fitted and coming off a roundabout to join a dual carriageway, put my foot down in 2nd and the car was fishtailing left and right, very lucky there was no one behind me. Seems the front bar caused more steering issues than the rear bar, also seems like there is alot less grip, car is jumpy over bumps at speed, and has completely lost that planted feeling it used to have. Although its better since I had coilovers fitted a few days ago, the bar is still coming off. Hope that helps.

Relative to the standard set up, a stiffer front ARB gives more understeer, a stiffer rear gives more oversteer. It's worth stiffening the ARBs all round, but if you want to dial out the oversteer stiffen the rear by more than the front.

My front bar just dialled out some of the oversteer caused by the stiffer rear bar... thus increasing the overall grip.
But the smiles per £ are much lower than a rear bar.

P.S. Young Bob, you should try mine... LoL

Similar to what I ran eventually on the Blob (JDM 370/360, road going mainly) - 24 rear set on middle (~25) & 22 front on stiffest (~23)
An Anglesey/Midlands run was pretty much the most memorable Impreza run ever on that set up, on coilovers too, which I normally hate

The only thing roll bar related that would cause it to be oversteery would be a SOFTER Arb having less body control and loading the outside wheel.
A perrin ARB on any setting on a 24mm bar could hardly be described as soft so I think that your handling traits is more likely to be a cause of other factors to do with rear toe, ride height, and camber all being huge factors affecting handling.
Backontrack in guildford set my car up three weeks ago ask Budgie, Maggy or any of the guys at the last meet - its on rails stays neutral and holds it position really well. I would say that £250 spent on a ride height, camber adjustment and toe settings front and rear would work wonders.
Back on tracks VX220 racecar won the MSV trophy this year and they run lotus elise racecars- Jez and his old man really know the suspension game. they have transformed my car.
For the record though my ARB on the back is on the softest (ie the longest pivot point away on the bar)
If you want to have a ride at the may MSOC then you are more than welcome.
Handling is a very personal thing as we all know but I know that a car that you dont have confidence in is not a car you like to drive fast thats for sure.
Are you running coilovers and camber adjusters too?

Yeah im sure going more then one size up without upgrading the fronts will upset the cars balance and might even lead to sum snappy oversteer @ high speed like that guy in the scooby on the last topgear
