    Semi slicks?

    Hi , I've got a car I'm doing track days with, it's a rwd, 900kg, 80-90rwkw. Trying to find a semi slicks in 195/50r15- or 205/50r15. I've got prices on federal rsr, and re71s, but havent heard anyone's experience with either. What about a050, or nankang ar1's? I've been told Toyo r888r aren't what they used to be? Thanks

    AO50s work great on Lotus so should be fine for your application if you can get the size you want.

    IIRC R888r are now all old stock. I'm not sure they are making them anymore. Nankangs are okay while they are "on" but they go off again pretty quickly. The RSRs and RE71s tend to be more for heavier cars.
    If you dig a hole and it is in the wrong place, digging it deeper isn't going to help.

      Can't go wrong with A050 or Z221. Nankangs are a good budget option but not as quick. You get what you pay for.

      Non r spec, the federal rsrr isn't bad, hankook rs4 and yoko ad08r a bit better. A052 a bit better again.

        Nakangs are heavy, go the AO50 for ultimate speed

            Speed costs...how fast do you want to go?

            If it's just track days for fun - go something cheap like AR-1. Haven't used, but many have, they work enough and last well.

            Medium price are something like Kumho V70A. I use and like.

            Must win, must spend = Yoki A050.

              Run RSRs in a stripped honda integra. Which at a guess would be very similar specs.

              They are not the most grippy on the market. But price vs life vs grip is pretty hard to beat.

              Also pay attention to the manufacture dates, get the newest set, have noticed this plays a part too.

                I've done one track day with Z221 softs on the RX-7 so far and they're much more impressive than I remember my R888s being when new. And this was on a very cold, damp day.

                  I've done 4-5 track days and 4 powercruises with nankang AR1. Very good bang for buck, nothing too serious. Little bit heavy.

                      I used Nitto NT01 (205/50/R15) on a car with very similar numbers to that. Lasted a full season - 24 races across 6 race weekends - without issue (well, they weren't really semi-slicks by the end of it, but still a full year on 1 set gave me nothing to complain about).

                        I did a full season with QTCC in the E30 using A050 Mediums. 205-50-15s on a car with 250 rwhp and 1000kg body weight (including me)
                        They got better as the year went on, and I ended up winning races in my last two meeting.

                            I can't afford either so i run AR1 on my barge 1500kg with driver, can't quite keep up with guys running the better stuff.

                              I like the Advan Neova AD08Rs. They're sometimes 4 for 3 at Bob Jane. I run them on a 1200kg Evo 1 as a 195/50/15 or a 215/45/17. On a fast road not much difference between the two.
