Hankook R-S4

[Wanganstyle]

Debating getting the R-S4s in 225/45/15 or Direzza DZ102 in 205/50/15 for my s52 e30 with 15x8 TRM-C1s.
Car will mainly be driven on the street, but potentially track or auto-x.
Huge price difference.. Is the increase in width worth it? any other recommendations?

Tires = handling

If you don't want the performance handling don't buy sticky tires

Could u post a side shot of those wheels? Thanks

Updated the album with a couple straight on pictures of the wheels, I realize now you probably want a full side picture too which I'll add when I get a chance.

Those are not even comparable tires. The RS-4 is going to have twice the grip but will probably last half as long. Depends on what you want, ultimate grip or longevity.

RS-4s came in yesterday. Going to try and get them mounted within the next week. Can't wait to see how they compare to the RS-3!

I'm running Bilstein Sports with Ireland Engineering Stage 3 springs, and Treehouse racing CAB's. I had to cut a slot into the wheel well plastic at the front to keep the tires from rubbing and I did a slight roll on all the fenders, no rubbing issues that I've found afterwards. I don't have a ton of pictures but this should give you at least a basic idea. Also if anyone is curious the Massive sport brake kit fits in these wheels.

Ordered my RS-4's for the Cayman this weekend. Had fun Saturday burning off the remaining tread on the RS-3's at an Autocross! I'll let you know what I think about the RS-4's once I install them.

[Bimmerguy91]

I would guess I've never hit the limit of my RS-3's so I think the RS-4 will be plenty of tire for me!

I'm just gonna do the RS-4s. Ordering them this weekend.

They are good. Very good

If you have never hit the limit of a nt01 or re71 then you'll feel the rs4 is amazing.

re71r and rs4 are close enough in lap time that its just up to the preference of tire feeling; if you are looking for something to run more laps then a NT01 will still be better; slower lap time though by about a second

Advan ad08R will be slower but more forgiving at the limit

both Nt01 and re71 last about 11-12 events for me; same car same setup
RS4 I will use later; ran rs2 and rs3 and still prefer the breakaway of the bridgestones better

cost between NT01, re71r, rs4 are close enough that if you want to get more money out of your track sessions (i.e. go for it entire session); you might as well just go Nt01 unless classing for competition restricts the TW

I actually was pondering using RE71R for a 100TW class because its ultimate one lap time will be 1-1.5 seconds than a Nitto Nt01 or Maxxis RC1 (both 100TW). Some friends are doing it with good results. RE71R is actually fantastic in the rain if at full tread; you can run them to the cords like a Nt01

I'm considering running the exact same wheel/tire setup this summer. Are you on stock struts or coilovers? Would love to see some pics too, if you have them.

You might feel quicker turn in response with the smaller wallz

Not so fast...you might want to stick with the 45's based on the rim size.

Remember, side wall flex plays a part in slip angle along with chassis weight and balance. short side walls don't flex much and don't allow for as much roll over, which to a point, is a good thing.

Based on what you say you are going to do, go with the 45's.

I run R-S3s on my Cayman S and LOVE them. Only negative is that they ride super rough before they warm up but that's not a big deal. Wonder if the R-S4 will outperform the RE-71R?

I've got a set of 225/45/15's on my 318is on Konig Hypergram 15x8.5 et25. Have to use a 12mm spacer up front to clear the strut but they fit on the rear with no spacer. I've only got 1 autocross on the tires and it was barely 50 and the tires only had about 100 miles on them so I doubt they were showing completely what they could do. I was impressed on the short time I ran on them though. Unfortunately I don't have experience with any of the recent 200 TW tires on this car, the last set of tires I autocrossed this car on were ancient Starspecs (first gen) and RE-11's.
