Now I'd had them on the car for a bit, played with the settings and done a track day I thought I'd write up a little about them.
My Fiesta ST is a 2013 ST-2 with the Peron V1 superstock turbo upgrade (so around 280bhp and 280lb/ft), Quaife LSD, MeisterR GT1 coilovers and PB 304mm 6 pot front brakes.
Running on AD08 tyres.
The MeisterR GT1 has 32 stage damping, the same as the cheaper Zeta-R set up I ran on my previous ST-3.
At 0 clicks, or full soft, it gives good ride control with all of the trademark ST suspension firmness removed. Especially at low speed.
The car is much more civilised around town, over lumps and bumps and to me personally is far better than how they come out of the factory for daily usability.
The Zeta is almost as good in this respect. Both set ups give you a much more compliant ride that makes upgrading to coilovers worthwhile.
At 32 clicks, or full hard, the GT1 is firmer than the Zeta. Imagine the stock ST's hard low speed ride a bit harder, then at every speed. It's firm.
On track it really came into it's own though.
It's firmer than the hardest you can get the Zeta and it performs really well on track. The car still had the traditional Fiesta ST qualities than make them so much fun, but with better control and better communication back to the driver of how the car was moving around.
Of course you can have any number of clicks you like, but I found on both the GT1 and Zeta full soft best on the road and full hard best on the track.
If I was going to use my ST just for road and fast road use, I would probably stick with the Zeta. For what you get (including camber adjustment) it's a well priced set up, giving a softer and better ride together with a slightly firmer ride if desired.
But if you plan to do track days and upgrade the car further the GT1 are a very good choice, with extra firmness and body control you can't get on the Zeta.
The fact that both kits come with camber adjustment included in the price makes them both a good price in my opinion.
I have been very impressed with both kits which I bought with my own money and not subsidised by MesierR in anyway.
As someone who likes track days the GT1 are a clear winner for me.
I tried them after fitting the same spec kit to my 1992 R32 Skyline GT-R where they have been are equally impressive on road and track.
