Default Dunlop Z1 Star Spec or Falken 452?

I am trying to decide between Dunlop Z1 Star Spec and the Falken 452. I use my car as a DD and currently running Falken 451 (245/40x17). I know that the Dunlops are about $30 more per tire, but I am really interested in any feedback you can provide with your personal experience with either/both tires.

The Star Spec is a good jump up from the FK452. However, you have to decide how much grip you actually need and will use. These extreme summer tires offer enough grip to where they are pretty much unusable on the streets without driving like a complete ass. The level simply isn't needed unless you do sport use with the car (auto-x, track, etc.) and can actually make use of the abundant amounts of grip. If you can't, you are many times better off with a longevity tire.

Thanks for the feedback....Anyone has information regarding the wet traction of the Dunlops? I know the fk 452 are pretty good in wet traction. How do the dunlops compare?

I agree with back road runner. the dunlops grip much better over the falkens but they more than likely wear faster because of this. the star spec is more comparable with the falken azenis RT's

Just save your money. I rock the 452 and they give me enough grip for the street, track and the auto cross. As Back Road Burner said, the Dunlops will have to much grip(and wear too fast) for just a DD car.

I was told here that the FK452 were not a good choice for the track. So, if your planning any track time you may want to think about that. FYI

If you track the car, I would recommend the Star Specs. I have the FK452s and was not impressed with their track behaviour. They were fine for the first event but it seems as if the grip level has plummeted with a bit of wear on them.

I haven't had experience with either tire but if you are considering the Star Specs, have a look at XS as well.

I have the star specs. I ran through absolutely PORING RAIN for over 100 miles and I did not have any trouble at all. There was several inches of water in the tire ruts and I never felt traction lacking. Visibility, on the other hand, was the limiting factor. Do not hesitate to buy the star specs on account of wet traction! I don't have any experience with that model Falken, so I can't make a direct comparo....

Thank you all for your feedback....I do not track my car, but I do drive spirited at times. I will sleep on it and decide in a week or two....

I have 235/40-17 Star Spec... they are LOUD! (you gotta expect that from Extreme Performance Summer tire )

We had some rain last week or so... they gripped pretty well in wet. I didn't really push them hard yet, but I will this weekend on my first track day!

FYI, Dunlop Direzza Sport Z1 Star Spec runs wider than other brand/model. Star Spec in 235/40-17 is almost as wide as my previous Bridgestone Potenza S-03 PP in 245/40-17.

Another tire to consider for street DD is Sumitomo HTR Z III (was my second choice). It's supposed to be equivalent to or better than Bridgestone Potenza RE050A PP but cheaper price.

Yeah, the Star Specs do run wide. When I ordered mine, I opted for the 235/45R17 based on Luke's recommendation. I do think that the 245/45R17s would have fit. When I stacked the mounted Star Specs up on the garage floor next to my 245/45R17 V710s, the Star Spec stack was 2-3 inches shorter.

I never thought of the noise level for the Dunlops...I actually put on Falken 451 and got rid of the RE070 because they were loud...So, I may look into the Sumitomo HTR ZIII. Thanks.

i just got some star specs- i'd consider them pretty smooth and quiet (coming from azenis st-115's, one of the quietest tires)

and they do run wide

only complaint is they are sticky and pick up every little rock on the road and sling it up into the fenders
