Popping up an old thread here but I just wanted to share similar experiences with my Eagle F1 Assy 2's..
So I recently got them fitted in 225/40R18 size at the same time with a B12 Sportline suspension on my mk5 GTI. First impression was that all the sharpness was gone from the steering as was the planted feel my GTI used to have (with Conti CSC3). This made me scratch my head for a while - perhaps there was something wrong the fitting and alignment of my new suspension? I took the car back to the garage where they checked everything and also did a realignment for me. None of this helped.. I'll add that I also tried playing with tyre pressures from 2.5 bar all the way to 3.0 bar. The feeling remained essentially the same except for all comfort being gone at 3.0 bar pressures.
I also chose this tyre based on a couple of tests where it would beat the Michelins and Continentals as well as the many positive comments on this forum. I should've done some more research earlier as I tried searching for issues what would cause this sloppy, wobbly, excessively yawing feeling on my car. It's the rear axle that feels really unplanted at higher speeds especially if you try the F1 style tyre warming up maneuver by flicking your steering wheel from right to left. The rear of my GTI now has this laggy yawing/swaying effect which I really hate. Also my car and especially the rear is now constantly moving sideways at motorway speeds if there is even the slightest of side wind.
Apparently despite the test results this is how the Assy2 tyre is - all soft and wobbly with no feel as I found out from quite a few other forum users' experiences. I do like the comfort and noise levels but I was primarily buying a performance tyre for my GTI when I chose the Assy2 and I have to say I'm quite disappointed with them. A performance tyre should make your car feel planted and secure. I don't really care if these tyres have more grip than the competitors if they give you this unplanted feel when I'm afraid to even try and take the tyres to their limits. You know what I mean?
I currently have about 300-400 miles on them. I really hope they start to feel better (or me getting used to the lack of feel) once I get some more miles in them.. The funny thing is my car felt absolutely spot on with standard suspension and my previous CSC3 tyres. Now that I spent a whole bunch of euros on my chassis and tyres (Eibach Sportlines, Bilstein B8 shocks, new front control arm bushes, new rear ARB dog bones and new Assy2's) it is actually a lot worse handling-wise. Do love the stance on the Sportlines though. :)
Also wanted to ask which tyres would you recommend for road use but with a more direct steering response and a more planted feel? I found the Conti CSC3 absolutely spot on in terms of balance between sidewall softness (ie. comfort) and steering feel/grip. Of course the Conti's wear awfully quickly. I have yet to try the Michelin PS3's - perhaps they'd offer something between the Conti's and Goodyears? I am really wondering why do people think this tyre (the Assy2) is so good..?
