Willie isnt that just stiffening the whole car without changing the understeer bias?

When you lose grip on a round a bout do you over or understeer on your set up? I only have a rear Arb fitted , front is stock but the car is very balanced. It will just about understeer first but a quick flick will bring oversteer.

If i was adam id do the rear first and see what it feels like.
No.

Having 25/25mm the car oversteered controllably a lot more. What changed this balance is when you start putting on rear struts and spacers.

youve compared this to stock plus rear arb? no spacers, struts ect.

Havnt run with a thicker front tbh. maybe you reach a point where adjusting the front stops affecting the back:shrug:

No I haven't personally unfortunately.

What I did was get ARBs done...noticed it oversteering nicely. I got rear strut and it oversteered less. Added spacers and it was more neutral, as I could go round corners very quick now I found on some scenrios it understeered and on some there was oversteer. Could be the tyres? Who knows.

You may be right...I got near enough every chassis mod there is now bar welding the subframe and roll cage. :)

Right then people having had a think [and reading up a bit] it seems pretty obvious that I need either a stiffer front or a matched pair that are adjustable........came to this conclusion due to the fact the LC doesn't have a rear ARB as standard therefor the front is designed to be stiffer?

The 2 options I have are the KW 23mm front and the whiteline 22mm adjustable rear

or

The Whiteline 22mm front adjustable and the Whitline 22mm rear adjustable


What are peoples opinions on these 2 set ups?

The KW front and Whiteline rear will save me about £30 and have a thicker front where as the Whiteline front and rear will be the same diameter but both be adjustable?


Also if I can't afford to replace them both together I could get the front done this month and the rear done next month......after all having just a front is no different to whats already on there?

I had a 28mm rear ARB (set to mid point) with OEM LCR front, S3 strutt upper brace (has lower as standard). This felt very good and did tend towards the oversteer.
Now with a 23mm front ARB, KWV3 and rear at stiffest setting it feel AMAZING.
TBH I haven't got near under or over steer since this has been fitted as there really is that much grip, even with one track day REALLY pushing on.

As I said I'd got either 25mm front with 22 or 25mm rear remembering the 23mm one on the LCR is more effective than on the LC

I dont have the option of a 25mm front tho due to there only being a couple that clear the DS's

I do however have option of a 23mm front and a 22mm adjustable rear?

or 22 front and rear both adjustable

I think 23-22 is what James is running?

Adam what front shocks do you have fitted?
Do these have the LCR drop link connection?
Are you planning on changing shocks soon??

Just budgets same as the Jamex ones.

Don't have the ARB connection.

No planning on changing they only done about 1000 miles


I can't afford to change them I'm only fitting the ARB's as its MOT time and I need 2 inner steering rack arms so the garage is going to change them and the ARB's together whilst its on the ramp.


Would the 23-22 or the 22-22 not be any good?

Its never going to be a track car but I could do with a bit more DS clearance so thought this was a good time to upgrade :)

The 23mm is the same size as the one you have fitted, TBH I doubt it is worth changing, just change the drop links and fit the rear 22mm ARB with S3 strutt upper and lower brace.
I'm sure this would see you happy with the handling

I have already changed the droplinks but it still just touches the drivers side DS over potholes hence the need for a ARB with bigger hoops.

The FK 23mm front also has uprated mounts so I guess this will help a bit over standard.......can't be any worse than whats on there.

I can't fit a upper strut brace as my intercooler pipe is in the way, would it be worth just fitting the lower?

Rear is not a problem alot of people seem to rate the Whiteline adjustable 22mm so I'll get one of them.


Seems to me that the aftermaket ARB's avalable for the LC are not very well thought out......you either have a thicker front that catches the DS or a thinner that doesn't but doesn't offer a performance increase :doh:

The lower one only would be better than not having it so yes. Can your intercooler pipe work not be 'adjusted'??

What are the MK4 Golf guys doing?
They have the same set up as your LC

I don't think a strut brace will fit even if 'modified'

The golf boys seem to all do different things, bit of a mix and match from looking on the UKMK4's forum.

To me common sense says that if its ok to just replace the rear with a 22mm and leave the front standard then fitting an KW 23mm front with a 22 adjustable rear can only make it better.

I can then in time add a lower front brace when funds allow.

Sound like a sensible plan?

Sorry to jump onboard... but I have no plans to upgrade the front ARB on my LC ... but would like to install a rear ARB.

What thickness ARB would be recommended?

Sorry Adam :)

Adam the handling characteristics of the golf are different to the Leon. Leon is more tail happy for sure.

I really wouldnt start experementing with different brands of ARB. From the sounds of it, you are better of going for the H&R kit for the cupra. its a 22/26mm configuration and works very very well. The rear is adjustable also.

My choices for yourself is
Eibach 25/25mm
H&R 22/26mm
Neuspeed 25/25 OR 28/25mm

The eibach one from what I have read is just standard but thicker so still rubs and no good
for me.

The H+R doesn't overcomr the rubbing problem either I don't think.

The neuspeeds are £500 and thats silly money in my opinion as I still have to pay to fit them

sounds like I'm moaning but I'm not I just dont have that much money to spend :)
