<p>Removing the arb causes more front roll just the thing you need to keep to a minimum for autotest. So you would need to go way up on front spring rate to compensate, the youtube you posted show the car very flat but plenty of dive when on the brakes. Keeping the front arb and going to softer springs as Dave A suggests should fix that.

So you would need to go way up on front spring rate to compensate, the youtube you posted show the car very flat but plenty of dive when on the brakes. Keeping the front arb and going to softer springs as Dave A suggests should fix that. I would start with keeping the rear leaves std escort saloon and a lateral link as the axle moves sideways a lot when autotesting. When the front end understeers then correct it with the right foot as in the vid. This should give you a 'flat' car that will spin, flick and j turn. This is somewhat different to what I have used for the road. (stiffer front, and soft rear). AS for caster and camber I would try for low caster angle to make it easier to steer then use a high ratio rack and minimum camber since you would have little roll then there would be little value in high camber angles and you don't go round corners fast any except sideway ;)</p> Cool - compression struts are…tag:duttonowners.ning.com,2017-06-30:2398922:Comment:2355682017-06-30T19:06:26.353ZRoy Kemphttps://duttonowners.ning.com/profile/RoyKemp
<p>Cool - compression struts are the ones that go rearwards from the TCA - does this not make them similar to your locost TCAs which go to a bracket behind the hub? Your solution looked very interesting.</p>
<p></p>
<p>When you say the front "tips up", do you mean transfers the weight over the front under braking, or am I misunderstanding?</p>

<p>Hi Vern, I'm certainly not getting upset about it, just seeing if there's a cheaper way to get softer springs and height adjustment onto the shocks that I already have. If there's an option, brilliant. If there's not, it can stay as it is.</p>
<p></p>
<p>I hear what you're saying - could well just be incurring a load of extra hassle to end up in the same cost ballpark as shelling out the money to Protech or Dampertech for something "proper".</p>

<p>Good into on the shocks, though, so thanks for coming back. I think the acid test will be to see if removing the ARB makes any difference to the suspension travel on the standard shocks.

<p>We've had good results with replacement fabricated lower wishobones to replace the escort TCA and removed the ARB altogther.</p>
<p>Had to add an extra chassis bracket each side and drill out the TCA mounting hole in order to use Locost style brackets/bushes. Considered Tension struts (not compression as they're the wrong way round) but thought they're way too expensive for what they are and also has advantage of not welding onto the TCA for the spring mounts either.</p>

<p>Adjusted the Caster angle while we were at it to be ~8deg for added feel - esp with PAS</p>
<p>Never had it on the track so can't compare too much but it made it to Stoneleigh and back no dramas</p>
<p>The front also tips up better than before</p>

<p>The Duttons I have encountered with mobike monoshox on (phaeton3 and melos) were fitted with 1.7"ID springs and had an open/closed range 8" to 11". They were replaced with AVO 080110 and 1.9"ID Suplex springs</p>

All the car dampers we looked at (BMC mini are quite short) are all too big on the damper body for the 1.7" springs. I suspect by the time you have bought suitable 'off the shelf' dampers, a coil spring conversion kit and new springs and whatever else you'd be back to the same sort of price as a Gaz set up.

<p>If anyone has an S3 Phaeton with these shock sitting closeby and possesses a vernier caliper, would you mind terribly nipping out to the garage and measuring the diameter of the body of these shock absorbers? I'm trying to see if there's an off-the-shelf option to fit a coilover conversion kit. I'm on an oil rig in the middle of the "Bumfuck, Nowhere" shipping region, so would appreciate the help!</p>

<p>Cheers in advance!</p>

<p>I'm not just 100% sure that the bike dampers can even be dismantled to take the spring off. I think they're a sealed unit. But, then again, would you even need to remove the spring to measure it, or just apply the same principles to the damper as a whole?</p>
