How long till I need to think re-enforcement

[elderlycoffee]

I've seen chassis reinforcements on sites like protege garage for the speed 3.
How much HP/Torque can the car handle before I need to think about these things.

Those reinforcements are just to reduce body roll, help in cornering, etc. We never gona have so much hp/tq that the chasis will brake or something.

The chassis does bend/warp over time. High power does make it more pronounced. However, Mazda did stiffen the frame of the MS3. So, do we need it? And when?

 

[redspeed]

Huh? (ugh) There are 500+ hp civics HB with little or no chassis reinforcements, with no problems. Stiffer chassis are only good for circuit racing, not drag racing. When you have a high power FWD your real problems are traction, motor mounts, axles, etc. I have never heard of chassis bending/warping problems, other than cornering stuff.

fwd cars dont have the same physics as a rwd car , a rwd engine moves side to side twisting in one direction while your differential wants to twist in the other, over time the body and frame twist , I had both a 465hp vega and a 700hp+ luv truck wich both ended up with doors that wouldnt shut right and other such problems, I have had friends with 400hp+ fwd cars and they just dont have those types of problems.

fwd engines move back and forth so the twisting force is in a whole different direction
