I'm satisfied with them. I've done about 900 km since mounting them, where about 100 occured yesterday at the track. In general, I'm impressed with the way they behave on bad roads, the noise level and the track performance. As you know, I have mostly used my GTV for spirited driving on twisty country roads so far. When I bought it, it had 7x17 wheels with Nankang NS2 tires in good shape and I considered them a positive surprise as well, both in terms of noise and comfort, but not grip... They were predictable but slippery. Once I fitted the Federal RSRs, I believe the noise actually decreased a bit, or at least changed to a slightly more enjoyable frequency, at highway speed (100-130 km/h) and they are definitely not worse in terms of bumpiness. As of today, I've run them at 2.7/2.5 bar front/rear on the road. There is one difference, though. The Federals tramline in a way that the Nankangs did not. On a normal Swedish highway, which maintains decent quality, the two tires behave in a similar way, but when you're on metropolitan commuting roads and country roads that are not as well maintained, the Federals are more nervous and require some attention. However, I don't usually drive cars with wide/nervous tires, so I'm not exactly used to it, but I still don't find the Federals unbearable in any way. It is to be taken into account that the Federals are 225 wide and the Nankangs are 215 wide, but the difference in stability is most likely caused by the more aggressive tire pattern of the Federals. It reminds you of Toyo R888s. What about yesterday's track event, then? Before I began my first laps, I lowered the pressure to 2.2/2.0 (= cold temp). I used intuition to find this number, then googled quickly to see what others have tried on the same type of car. Seemed OK, so I stayed there. Keep in mind that this was my first time on the track with this car. I started out carefully, getting to know the car and the track (haven't visited it in almost 2 years), gradually increasing the pace. Here is where I was impressed with the Federals, not only for one but two reasons. First, they were predictable in their behaviour, signalling clearly when they were about to let go. Second, they were very consistent as I kept counting laps. With rising heat, their grip level stayed virtually equal. They did not get slippery and edgy as the heat rose but stayed grippy. It remains to be seen how they last over time. Note that my car is standard chassis-wise. I still haven't fitted my Eibach camber bolts and I still haven't made my mind up and ordered an FK Silverline X coilover kit It's important to point out that the car rolled a lot in the corners, as it's soft both laterally and longitudinally. Of course, the camber in the front is far from ideal, but the Federals were still strong enough to cope reasonably. As you can see in the photo I posted before, most of the top layer of "hairs" on the shoulder of the front tires are gone, so the camber should be increased. It's possible that they would have benefitted from a few extra hectograms of air in the tires as well, though I never measure the tire pressure when they were warm. I'd definitely recommend the Federal RSRs if you use your GTV for enthusiastic driving on winding roads and on the track. For twisty roads only, there are probably better alternatives from "the big dragons" of tire manufacturers. Similarly, for pure track use, a full-spec R-compound tire like the R888, Yoko A048, Kuhmo V70A, MPSC, or why not try Federals FZ, copes better and most likely lasts longer. If you're just in it for the smile and don't mind every last tenth on your lap times, the RSRs are a genuinely good choice. How was that review, Mr Svendsen (and all the rest of you )?
