Just to add some additional info to this thread now that I have had time to reflect on the upgrades. I have purposely been taking it easy with the car for the last week. This has been for 2 reasons..
1. New bits(especially race/track orientated bits) on the suspension often have a habit of coming loose after a few miles. So we marked all the fasteners with a line of paint when we put them on, so we can check to see if they are winding themselves loose. News is.. Anti roll bar drop links locking nuts have, these are the second nuts on the thread that are used to lock the top ones up.. Bit of Loctite and now all is good. The first locking nuts didn't come loose which is reassuring.
2. I wanted to build up to and understand what the car was gonna do with a much stiffer back end, no point in binning it into a hedge when it gives you a big over steer moment that you aren't expecting..
As we all know the weather has been awful the last week. really wet, tons of standing water and all the grip issues that are associated with it.. So.. Gave the car a bit of spanking last night as it was a bit dryer and these are my thoughts.
1. First the front end. Now that the front suspension geometry is effectively fixed by using the uni ball front arms and uni ball drop links, front end grip is excellent. Much better than before. So much so I didn't see the traction control light, traction out of corners has improved significantly and there is no more woolly feeling that was there previously, where you had to try and guess how much lock was needed for a given line. The fixed suspension geometry has also translated into a much more stable car on the brakes. No more wandering and skittish application of the ABS as the front arms were moving around underneath the car. My advise get some, a definite pre LSD upgrade. Can't wait to get a LSD in the gearbox now, it's really gonna complement these suspension bits. When really pushed the car does it's 'slight reduce power' thing, but the traction light doesn't come on. Figure this will get sorted with the LSD upgrade.
2. The back end. Much more playful, you can feel it starting to move very progressively on turn in to the apex. There is a particular corner that joins the motorway on my commute, it is effectively 70deg constant radius, quite tight. Where before the front would try to wash out and the car would not turn in, now it just turns in, you get on the throttle and you feel the chassis move underneath you as the back is moving out, but it doesn't let go, just tightens the line and then you are through the corner.
3. Overall. really nice balance when pushing on, back end is now doing what it should be, moving around to let the front drag it through the corner, although there is still some understeer is this now more dependent on how the turn in phase of the corner is approached. 100% improvement in chassis dynamics. Can't recommend this stuff enough..
