The dry grip is great. The handling is very good and stiff, while the comfort is not bad. I recommend them for the track up to 10 degrees C - they start to melt during warmer days after few laps.

Great tyre but noisy
Only lasted 13000km of spirited driving
Cheap alternative to tires like
1. PS3
2. Assy 2
3. CSC 4

They're great on the dry with a lot of grip, but they're terrible on the wet. Aquaplaning is quite dangerous. They're cheap compare to other semi slicks (200 tread wear). Changed these tyres because they're cracking and split sidewall after 3 years, even though had travelled less than 10,000. Sidewall literally crumbles like parmesan. They're good if you used them for track day car and use them up very quickly for a couple laps until they're bald, but do not buy them for your everyday car because they will not last long (mileage or age of the tyres).

Review your Achilles 123S >

The first thing i bought this tyre its because the price is literally CHEAP! and its a SEMI SLICK, using it for daily driven Honda Fit, but the tyre is not long lasted and its little bit noisy if you still using a "stock exhaust"

Been using it for a while, good choice for low budget, amazing dry grip but really slippery on wet track (i have to lower the pressure to maintain optimal grip on wet surface), worn out easily(a bit softer compund maybe?), bit noisy(a lot less noise than the predecessor 123), but overall its good because of the value for money, would buy again, shred your tyre not your wallet

Used three sets of 123s driving on mountain road and highway.
Good dry grip sustained until no tread depth,compared to
AD08 it's less stable during intense driving.
And the wear of tires are seriously may be related to the soft rubber.
It is still a good choice in economy.

Not sure if the compound has changed on these but back in 2012 I used to struggle to get wheel spin in a 300 rwhp Nissan S15 using 235/40/18 or 265s. A possible newer compound tends to feel greasier but still providing good grip when slightly warm to optimal temps. Even on mild days I would start to get wheelspin I would launch from the wheelspin even faster, but not anymore.

Since late 2013 and now on 340 rwhp, it's not the same, even if I lower the acceleration. I used to be able to plant it and rear would barely squirm, make the "screech-ech-ech" launch noise and rocket off.

Due to the wear rate on the rear, I am using the Achilles ATR Sport V2 for street. Not a bad tyre but around 20% less grip when warm than the 123S currently, less noise (123S are quiet until they heat cycle too many times), cost 30% less and coping well with some spirited squirts.

I'll be trying either the Dunlop Direzza Z2 Star Spec, Yokohama AD08R or the Hankook Ventus RS3 Z222 next.

It's always good to try new tyres and test their technology. I still think the best overall tyres I've ever used for sprited street is the Toyo Proxes T1R but not a cheap tyre and prboably due for a refresh rubber technology soon anyway (T2R?). Yet to try the competition's range to confirm though.

Love these tyres got them fitted to my impreza turbo very sticky, not really drove hard on wet surface but dry omg.

Cant get use to it, nice tread pattern though. Rear Only

Good grip even in wet. Great on dry.
If u're looking for a set of grippy sticky semi slicks and have a budget to meet, these are great. However they are noisy and due to higher rolling resistance, does consume more fuel.

not recomended for daily use. wear: suck as hell. because its semi slick. noisy after goes 40km/h only can use it under 6 months. affordable prices if u going racetrack/drag budget tire than other brands.not recomended use wet condition as it will slip.

Recently bought it & travelled 500KM on it. I do admit it will take another 500KM to fully see its potential but so far, grip on both dry & wet is awesome. It is semi slick, usable on both track & daily driving. There is a whizzing sound when you break during mid-high speeds due to its aggressive grooves. The tyres looks really aggressive by the way. Price wise, certainly way much cheaper than the usual brands. Would certainly recommend it & will purchase it again.
