HI there
Not really done an update for a week, but I fitted the 23mm front spacers last week which not only transformed the look but also dialled out the additional understeer the fitting of the rear 15mm spacers induced. The only downside if it exist is the car is maybe a hairs whisker slower to respond to steering inputs, but the rest is all positives as the cars balance is now spot on as front-end grip has improved. Infact the grip levels this car has in the dry are nothing short of mind boggling even more surprising considering the Pzero tyres are nothing special.
So today I fitted the remainder of my handling modifications, the larger anti-roll bars from the Ford Racing track kit I purchased.
We started at the rear and this was very easy to do, took about 45 minutes:
Rear stock GT PP bar is 22.5mm
Rear FRPP Race bar is 25.2mm installed on softest setting.
Then moved to the front, three bolts are undone from the top and the one under the alternator on the passenger side is undone with spanners from underneath. You then have to wriggle the bar out but it came out easier than expected.
Front GT PP bar is 32mm
Front FRPP bar is 37mm set on softest setting.
The white stuff in the pictures is energy suspension lube, I like to use plenty.
Driving the car with these bars on have certainly eliminated body roll, car is now totally flat and my biggest worry was ride comfort, no fear as the ride comfort is un-changed.
So the car is flat, it changes direction better, they have certainly improved the already high grips levels even further and confidence level in the car is now much higher. The car is just so sure footed and the handling balance is spot on, get a little understeer, just add a little more lock and it will took in and the rear stays planted. Now on corner exit one has to try harder to break the rear loose and when it breaks away the car is hugely progressive and controllable, more so than the M3, its a joy.
I think on a smooth flowing track like Donnington the Mustang would be quicker than the 911 and even the M3, with the 911 only having it in the wet. I am rather shocked actually with the corner speeds this car can achieve and the grip it has in winter and on tyres I am not so fond off. Makes one wonder what the car will be truly capable off in warmer weather with wider better tyres.
So what is left?
Well when I lowered the car the springs dropped it a little to much in the back, though the addition of the spacers pretty much eliminated that look there was still a hint of reverse rake as the arch gap in the rear is marginally smaller than the front arch gap.
So I shall address this next week:
Ignore the springs, those are clutch assist springs, 35lb and I fitted one it fits perfect and clutch has all the feel of using no spring, but pedal effort is not as much and pedal returns right to the top.
More importantly is the two purple coloured disc, these are spring spacers and one something I learned from BMW E36 and E46 owners where BMW would sell the spring pad/isolator in 5mm, 10mm or 15mm to adjust the rear height. So I have got a pair of 8mm spring spacers, they will fit between the spring isolator pad and body. 8mm however does not translate into an 8mm increase in height because the spring is not on the shock in the Mustang, so there is a leverage ratio, so an 8mm pad should give me a 10-12mm height increase, just shy of 1/2 inch. This will give the car the rake look I want as rear arch gap will match or be greater than that of front. It wont impact ride and handling wise the impact would be that of rising rear ride height with coilover so better turn-in and more bias towards oversteer, but I probably won't be able to notice.
Then all is left handling wise, though its more for looks is the front splitter and Shelby or Steeda rear track wing, they will add downforce but most of all look really nice. Then of course some lighter, wider wheels with better tyres will have all handling and aesthetics completely. Time for power then!
