DanGTI Posted December 27, 2004 Report Share Posted December 27, 2004 ok, got a loop GTI, will be buying coilovers....need to know if I will actually benefit much from an aftermarket ARB? Im wondering if the coilovers alone will help get rid of most the bodyroll anyway, or if they wont really make any difference to that side of the handling. (If its not really going to help I could put the money towards a BMC / more expensive coilies instead).Anyone here thats been in cars with / without an uprated ARB - much difference? How do coilover owners find bodyroll with the coils fitted (over the car on standard set up)? Quote Link to comment Share on other sites More sharing options...
Red Lup Gti Posted December 28, 2004 Report Share Posted December 28, 2004 to be fair, if you do uprate the roll bar (22mm) i think then u will prob encounter more understeer when pressing on into roundabouts and such, i am running the fk konigs (80mm drop) and although the ride hight is not to everyones liking it does handle like nothing else in the twistys!! I was thinking of a 23mm hardened volkswagon motorsport one but i get enough understeer as it is when i am pressing on and didnt really want to increase it. Coilovers will decrease body roll dramaticaly and depending on what rebound adjustment you have too. Quote Link to comment Share on other sites More sharing options...
ArosaMike Posted December 29, 2004 Report Share Posted December 29, 2004 Yeah....a stiffer ARB improves the sharpness of the turn in, but it decreases your overall grip. The Lupo chassis is really stiff so if you up the damping you should find it will reduce roll enough whilst keeping the grip style="vertical-align:middle" emoid=";)" border="0" alt="wink.gif" /> Quote Link to comment Share on other sites More sharing options...
1.8T Lupo Posted December 30, 2004 Report Share Posted December 30, 2004 The theory is that stiffer anti roll bars at the front will make the car understeer....but with most standard(ish) cars there isn't enough negative camber so every degree of body roll that the anti roll bar stops is a degree extra negative camber so actually gives more front end grip.This works upto the point at which the springs are sufficiently stiff to stop the body roll. But at this point the springs are so stiff that the dampers cannot cope and grip is lost.The best set up I have found is to stay with soft front springs and big `anti-roll` bars...that gives mega front end grip....

badger5 Posted December 30, 2004 Report Share Posted December 30, 2004 hardened 23mm front motorsport one?where do you get one of these from?rear has none as std on Gti or does it? (1.0 model has none)Eibach only list front which seemed odd :?: Quote Link to comment Share on other sites More sharing options...
Red Lup Gti Posted December 30, 2004 Report Share Posted December 30, 2004 hardened 23mm front motorsport one? where do you get one of these from?1.8t lupo was getting rid of some around a year ago! pm him and see if he has any left :wink: Quote Link to comment Share on other sites More sharing options...
Tigzâ„¢ Posted December 30, 2004 Report Share Posted December 30, 2004 Ive just picked one up off him today style="vertical-align:middle" emoid=":D" border="0" alt="biggrin.gif" />Its a GTi one, but I think the GTi one will be more than enough wont it?

1.8T Lupo Posted December 30, 2004 Report Share Posted December 30, 2004 Standard Lupo is 17mm, GTi is 19mm......the one I bought to you this morning tigz was on my Lupo Cup car which I thought was a 19mm, but I tried to put a 19mm spanner over it this morning and it didn't fit so Could be bigger...or could have extra thick powder coating on but I didn't have any bigger spanners or a vernier to check, either way it is bigger than a 1.0L Lupo bar.I do have an extra special "Carvell Motorsport" 1" diameter `anti-roll` bar which we made for the 1.8T....it is EN30B bar which we bent to suit our car....it would go striaght through the exhaust on most cars but would probably fit a 1.8T like your Bill.....it would take a bit of fabrication work to hook it up, but a good starting point.

1.8T Lupo Posted December 30, 2004 Report Share Posted December 30, 2004 I think it is 19mm, but as I said I couldn't fit a 19mm spanner on it this morning...probably due to powder coating though.The Lupo Cup cars did have a H&R bar bolted in the channel in the rear beam, but I took it out and welded a T45 tube in there....they were a bit of a bodge job though because they used massive spring rates to control the body roll which made then like a roller skate and crap on the brakes.

I want to retain the suspension compliance on `as-is` springs/dampers, as this works well on my ibiza, and get the ARB's working on roll control.What sort of spec is your car now then? I guess it started life as an ex cup car then? Quote Link to comment Share on other sites More sharing options...
Tigzâ„¢ Posted December 30, 2004 Report Share Posted December 30, 2004 Eibach frontI heard a rumer that a Lupo GTi front ARB bar is the same size as a Eibach one.Thats why they only list a Sport and not GTi. Quote Link to comment Share on other sites More sharing options...
Dogwood Posted January 4, 2005 Report Share Posted January 4, 2005 GTI front bar is 23mm diameter but design is not great. Has a large `U-bend` in it to clear the exhaust. Rear beam has integral bar welded in channel. Have'nt measured it but looks 25mm ish.Bill. I'm going to see about getting some bars made shortly. I'll keep you posted.

I'll keep you posted.Cheers Nick.I have a nice section of 1.25" Od 316L 0.125"wt tube which is crying at me to make a rear ARB out of it... LOLBolt in like Shine Racing ones.. (sounds like H&R one also, not that I've seen one.)you thinking front and rear Nick? Quote Link to comment Share on other sites More sharing options...
Dogwood Posted January 5, 2005 Report Share Posted January 5, 2005 Yup. Maybe +25% on the front so I can drop the spring rates and an additional one for the back just to perk it up a bit. There's a bloke based at Silverstone thats done some for some of the Kumho BMW boys and they are spot on. Just need to find his name. Need to get some toe in off the back as well. That tube sounds ideal for an in channel rear though. Is this your good lady's car you are hacking up?! Quote Link to comment Share on other sites More sharing options...

1.8T Lupo Posted January 5, 2005 Report Share Posted January 5, 2005 I think the bloke at Silverstone is probably Mardi Gras Motorsport? They make a lot of bespoke `Anti-roll` bars...they are also a good supplier of Carbon Metallic pads for the Brembo calipers. Quote Link to comment Share on other sites More sharing options...
DanGTI Posted January 5, 2005 Author Report Share Posted January 5, 2005 i think after reading this ill leave the arb's that VW chose to put in and just get the coilovers cos i dont want to lose grip on corners Quote Link to comment Share on other sites More sharing options...

BUT.. both work very well from cold, no worse and IMHO better than std pads from cold, and significantly better when warm (which does'nt take long at all)Downside? and there has to be one... extra friction from extra stopping power produces more dust (CM pads) and more heat..I boil my brake fluid, I dont fade my pads these days. They just keep working. Quote Link to comment Share on other sites More sharing options...
Dogwood Posted January 6, 2005 Report Share Posted January 6, 2005 Bill, thats cos your coming in from warp factor nine. What you need to do is give the Biza suicide doors that open and close from a microswitch on the brake pedal!What you got planned for the Lupo?
