I'm really happy with how it handles now and the ride actually isnt bad unless its a really bumpy road. At this point the biggest issue i'm having is the temperatures out here in Nevada and Southern California. I can usually only make it 1 or 2 laps before the car goes into limp mode. I'm looking into getting a custom radiator made by a local shop that will be able to withstand the sustained full power of the vehicle. Ideally i'd want to get the gearhead turbos and some downpipes at some point but theres no point in adding power when the cooling system cant withstand the current power in track conditions.

Quote from: P71Nero on May 05, 2022, 09:49:34 PMHello, I have a 2013 Lincoln MKS EcoBoost I've been using as a track car. Mechanically almost identical to a Taurus SHO. The adaptive suspension the MKS is equipped with may have a sport mode, but it's not suited to this kind of use. My shocks were all either on their last leg or completely dead, so I ordered some of the BC Racing DS Series coilovers. Their default rates are 6kg/mm front, 8kg/mm rear. 8kg/mm seemed much too soft for the rear though, as I had taken measurements of the rear control arms and found that the motion ratio was 0.578. With this, I found the rear spring should be at least 12kg/mm, and I decided I wanted to use a 14kg/mm spring.The problem is, BC doesn't have options for the rear rate. The rear springs are not a conventional spring design. I ordered the coilovers from their site with the 12k rear spring and I was told they only had an 8k that would fit the car. So I went with that, and looked for a way to adapt a linear coilover spring to the rear. I discovered that the 350Z uses a rear spring of the same dimensions in BC's kits, but they also have an option to get the 350Z coilovers with a lower spring perch for linear coilover springs. These perches can be ordered separately (D-17-LSA), so I ordered them along with some 7" 14k Swift Springs. (As of August 2022 I have gone to a 14k front/28k rear setup)They do in fact fit the car and seem to work perfectly. I haven't track tested the car yet with the new setup yet, and it still needs an alignment, but if I do ever need to change rates in the future I will now be able to use whatever rate I want for both front and rear.
