Trent,

About Z

Some good observations about Z here. There is long time I have decided to ignore his comments and respond to his useless sarcasms. Too bad he lacks some respect and basic manners because some of his engineering perspectives could be useful.....although to my knowledge these perspectives have never been confirmed by success on race car he built or teams he worked with. That is true that to successfully work in a racing team you need some positive attitude and some communication skills.....

To all,

About front and rear ARB

Ask your driver about the car balance; let's say he tells you he has is O/S. You need to increase your TLLTD by either stiffening your FARB or softening your RARB. Which solution will you choose? To make that decision, ask your driver a second question: is your car too nervous or too lazy? If it is too lazy you need to stiffen your FARB, if it is too nervous you need to soften your RARB. Now what do you do if the car oversteers and is too nervous and you do not have any RARB? You will need to soften your rear spring and that will destroy you ride and pitch targeted frequency. That is a reason why most race and passengers cars have frotn and rear ARBs

About high speed damping and blow off

Lest' be serious and practical: what do you call damper low speed and high speed? At what damper speed do your damper reach the blow off speed and where on the circuit? If you do a damper histogram you will see that on a FSAE you probably spend 80 % of the time between - 50 mm/s and + 50 mm/s. That is usually what damper guys call low speed. There are a few little bumps at FSAE tracks but these are not Sebring bumps, chicane curbs at Long Beach or WRC special stage junps....
