Oem ARBs?

[cem_gti]

I am not sure the S3 oem front and rear anti-roll bar mm's. I think the rear is 15mm what about the front??? And also i want to change the rear bar like 19mm or a larger bar. Is the rear bar woth it?

I think its 20mm front and 14mm rear as OEM. I heard that R32 arbs are good mod for S3 and those are 23mm front and 19mm rear. If you are changing only rear arb, then i think 19mm is too large because then it´s almost same diameter as front.

I believe its 15mm rear on the S3, the TT is 14mm rear AFAIK

I went for 19mm rear and 22mm front, Neuspeed bars (smaller fron tthan r32 but r32 has a v6 engine out front!). I also believe that the R32 bars are subject to a ridiculously long back order status.

From what I have heard, if you just do the rears, as Teemu says, dont go 19mm - check out the V64 motion rear bar, its 16mm

Thanks for the information. My problem is understeering. If i am going to adding a thicker front bar will make the car understeer again. It seems maybe 19mm is very large but i did same suspension setup to my focus st170 which has oem front 21mm and rear 21mm. I changed the rear with 24mm h&r rear bar.Understeering was reduce very much.Then i changed the frontbar with a 19mm(focus rs bar), the understeering was nearly gone. The only problem was if u throttle off or brake hard when hard cornering, there was oversteer but not problem...
I like the oversteer more because its my driving style.
I did a test again yesterday. I removed the front bar(entirely). And i like the handling when hard cornering:) Firstly i am going to buy a 19mm then we will see which upgrade for me.

Has anyone tried those H&R ARBs?
Those are 25mm front and 21mm rear. Do you think that those are too thick?

Wow! Those are thick ARBs. I wouldn't mind giving them a try, but they're a little pricey compared to the R32 ARBs. Although I bet you wouldn't have to wait untill May to get them.
