The 205 ECS is the same width or wider than many other brands in 215. I would choose the 205 ECS over most available 215 tire choices for performance, wet/dry grip, and ride quality.

My mistake, you did say the FORCE tire and your post was clear. Tirerack's rating system is usually pretty good. I did back to back testing (wet and dry track) with the Indy500 and the EC SPORT and the Indy500 was terrible in the wet. iirc, tirerack's rating system reflected my experiences...

So a 2,550lb 235hp BRZ with 255 Nankang CR-S tires and some aero just did a 1:53 at buttonwillow...

Indy500s are terrible in the wet. EC Sports are SIGNIFICANTLY better in the wet. Are you talking about mixing matching tire brands front and rear???

Just check it! "Cam Timing versus Valve-to-Piston Clearance: The exhaust valve is generally closest to the piston at 10 degrees BTDC, while the intake valve is generally closest to the piston at 10 degrees after top dead center (ATDC). Given these clearances, it should become obvious that...

Depending on timing, we could run your engine on my harness and motec

Cam design has changed and improved a lot in the past 20 years. I would be using a modern Honda-specific cam design. Cams are far more complex than lift and duration alone. There is a lot to the rate the valve lifts off and sits back down into the seat, how hard it is on the springs, and the...

Good info

Custom cam blanks aren't limited by the dimensions of the OEM cams (which regrinds are) and the only company that really makes cams for the NSX is Toda, and their profiles are old and very modest/conservative by modern cam design standards. There is a lot of perfrmance to be had whether NA or...

I might be doing a thing:

"Spring perch" (upper) and (lower) "damper body perch" are a little more accurate and better terminology for the two adjustments that affect ride height. A spring's "free length" is the length of the uncompressed, static spring. A spring's "preload" is statically compressing the spring at the...

Hmmm might be adding to this later.

s If he puts a 97+ rear caliper (48mm) on his current setup, his brake bias will go from a front-heavy bias of 62.1% down to a 55.7%. I need to go back through all of my notes because I think the 97+ NSX has a proportioning valve that brings its static 52.2% up to 60% front bias. More front...

I'm not familiar with that brand. So the Modena's caliper has a 42/38mm pistons in it (vs 40/36mm for the commonly use "Lotus" caliper. When combined with a 320mm front and 330mm rear rotor, the brake bias of your setup is 62.1% front bias. By comparison: 91-96 NSX = 60.3% 97+ NSX = 52.2%...

The JDM gears really improve the cars performance below ~95mph. Above that and the US ratios are actually closer together and result in better lap times and acceleration. The JDM gears also keep the engine in VTEC "more" (below 95mph), but does not prevent the engine from falling out of VTEC...
