Tony Posted January 4, 2009 Report Share Posted January 4, 2009 Lets be very careful.... If others have installed the uprated arb's without problems then great, but for now my concerns are evident but would diminish if adjustable drop-links where available (which their not) so i am worried about the transitional torsional rates front/ rear!... One of the tools i use to dramatically change a cars turn in is the torsional disparity..... food for thought!! Quote Link to comment Share on other sites More sharing options...

One of the tools i use to dramatically change a cars turn in is the torsional disparity..... food for thought!! Done abit more research and it seems the 19mm rear ARB has no problems but the 21mm snaps the brackets off after a while as they weaken, meaning the rear subframe needs reinforcing to prevent this. I've also read a few comments on how the car doesn't understeer as much with the 21mm ARB fitted, so maybe it does cause more oversteer which could be a problem? I've been put off now anyway from what could potentially be alot of hassle! I think the best route to take is change the ARB to a MK1, which will still be 18mm so I can poly bush the drop links for those. From the 2 photos I posted before do you think it would be worth my while doing this, especially as the type I have snap easily. Like you say there are no adjustable links available so I see this as being the next best thing. Quote Link to comment Share on other sites More sharing options...
Tony Posted January 4, 2009 Report Share Posted January 4, 2009 "snaps the brackets"... nuff said. I would be happy if you just up-rated the front arb and "poly'd" that.... this would reduce the float and tighten the corner in yaw. Quote Link to comment Share on other sites More sharing options...

There are no front uprated ARB available though but mine is already poly bushed Next step is the front strut brace then Quote Link to comment Share on other sites More sharing options...

Another little bit of modifying in the grand scheme of things shouldn't be anything to worry about. Very easy to box the brackets and then you have a 21mm rear sway bar.

Rich Posted February 10, 2009 Author Report Share Posted February 10, 2009 Back on to this subject...I've been looking at rose jointed front and rear drop links, which a guy in America makes. The front's are adjustable by around 1" shorter and 1" longer than OEM...will this be adjustable enough Tony? The rears are slightly adjustable but I would mainly want those as mine are prone to snapping, talking of which so are the fronts or at least bending! It would mean finding the older style ARB so they fit, which shouldn't be too much aggro. The fronts are $70 and the rears are $40, plus $40 shipping = around £100 So any opinions/thoughts about these? Fronts Rears Quote Link to comment Share on other sites More sharing options...
Rich Posted March 24, 2009 Author Report Share Posted March 24, 2009 My Eibach springs are on the standard shocks at the moment, new genuine front ones were fitted with the springs and the originals are still on the rear. What benefits would I get from upgrading them to sports shocks, say the spax adjustables? If these are also shorter would it help with my camber/castor issues?

No it would make it worse plus you would definitely need adjustable links. Quote Link to comment Share on other sites More sharing options...

I was thinking about this again earlier and thought the same...shorter shocks would mean more negative camber, so when this is adjusted the castor will be further out? Would it be a drastic change do you think? Quote Link to comment Share on other sites More sharing options...
