The CSR2 Dyno Bracket Map: Where You Get Matched

Live Races pair you against cars with a similar dyno time, not a similar real time. That single design decision is why the mode feels unpredictable, and it means your dyno figure is not just a number on the tuning screen — it decides who you face.

Where the cars actually sit is worth mapping. We split all 925 Tier 5 cars with a dyno figure into brackets 0.2 seconds wide and counted. The field is nothing like evenly spread.

Twenty-two brackets, and most of the game is in ten

Tier 5 dynos run from 6.534 to 12.241 seconds. That span needs 29 brackets to cover it. Only 22 contain a single car, and the distribution inside those is extreme:

Between 6.8 and 8.0 seconds the field is a wall. Six consecutive brackets hold 132, 131, 100, 93, 128 and 83 cars. Move outside that range and the population collapses.

The sparse brackets are where the game gets strange

Seven brackets hold fewer than five cars. Two hold exactly one.

The 6.4 to 6.6 bracket is the interesting one, because it is not sparse through neglect — it is the elite end. Four cars in the entire game have a dyno that quick. If your car is there, the pool of comparable cars is tiny.

The sparse brackets at the slow end are different: those are outliers and part-built cars, and there is very little company either way.

The finding that actually matters

Here is what the bracket structure does to a race. Take the busiest bracket, 6.8 to 7.0 seconds of dyno. It holds 132 cars, 129 of which have a recorded real time.

Those 129 cars record real times from 6.511 to 7.001 seconds. That is a spread of 0.490 seconds inside a bracket that is only 0.2 seconds wide on the matching criterion.

So two cars can be matched as near-identical on dyno and be half a second apart when they actually run. In a game where the whole top ten is covered by 0.074 seconds, half a second is not a close race — it is a walkover.

This is the entire reason Live Races feel arbitrary, and it is not bad luck. It is structural. The matching uses the number that predicts a clean run; the race is decided by the number that reflects a driven one.

What that means for your dyno

Two cars with the same dyno are not equally good opponents, and two cars with the same dyno are not equally good choices for you. The question is where you sit inside your own bracket.

• If your real time is near the fast end of your bracket, you are in a strong position. The matching will keep handing you cars that predicted the same and deliver less.
• If your real time is near the slow end, you are structurally disadvantaged. Every match is against cars that look equal and are not.
• A small dyno change can move you between brackets. Moving from the slow end of one to the fast end of the next below is a real tactical gain, and the brackets at the edges are far less crowded.
• In the sparse brackets the matching has little to work with, so expect less consistency either way.

Our Live Races tool does exactly this calculation for a specific car: it finds everything inside the dyno window and shows where your real time lands against them.

There is a second-order effect worth noting. Because the crowded brackets contain so many cars, they also contain the widest range of real pace — the 6.8 to 7.0 bracket spans 0.490 seconds of actual performance. The sparse brackets, with four or five cars, are far more homogeneous simply because there is less room for variety.

Why the field clusters where it does

The pile-up between 6.8 and 8.0 seconds is not an accident of the data. It follows from how Tier 5 is built.

A fully built, fused Tier 5 car converges on a narrow performance band — 100 of the top cars share three PP values and nearly two thirds of the global top hundred sit inside a hundred-point EVO window. When most of the field is built to a similar ceiling, most of the field predicts a similar time.

The long sparse tail below is the opposite: part-built cars, unusual models and a handful of entries that look like data problems. Those have no crowd to join because nobody else has stopped in the same place.

One consequence for anyone deliberately tuning their dyno: the edges of the crowded zone are the most useful place to aim. Sitting at the fast end of a busy bracket gives you a large pool of opponents who predicted the same as you and will mostly deliver less.

The short version

• Tier 5 dynos span 6.534 to 12.241, but 832 of 925 cars live in ten brackets.
• The busiest bracket holds 132 cars. Seven brackets hold fewer than five.
• Inside the busiest bracket, real times span 0.490 seconds — more than six times the gap covering the game's entire top ten.
• Being matched on dyno is not being matched on pace, and the gap is largest exactly where the most players are.

Every dyno figure behind this map is in the record database, and you can sort by it to see your own bracket filling up around you.
