So... In fact, F cars are already very stiff... Except some extremes like supercars, F cars are stiffer than most of the cars on the roads (Why all of a sudden, I feel I was dumb???)

Hopefully, Lexus can continue to build F cars in the future!!! (I think many people including me were fooled by those stupid reviews!!!)

Now, all we need to do is... Totally ignore those stupid comments and BELIEVE YOURSELF!!!

I think RSR lower springs at rear for the first generation NX could be a bit stiffer than OEM. (In general, Ohlins should be 100% stiffer in spring rate or 41.4% higher in ride frequency than OEM)

The RSR spring rates for the second generation NX should be more closed to OEM's. Therefore, NX's ride frequency should be similar to X4's and lower than Lexus's or BMW's sedans...

PS:Not sure why car makers lower down the ride frequencies for their SUVs... (SUVs are high off the ground which is bad for the car handling, so supposedly they should have stiffer suspensions)

If you upgrade your suspension to stiffer one, please always remember "DO NOT GO CHEAP ON YOUR TIRES!!!"

The stiffer suspension will quicken the responsiveness of your car but may also reduce the grip level on your car. It would be recommended that also upgrade your tires at the same time...

(Some tires could last longer but this also means that those tires are less sticky!!!)

PS: I guess the reason why car makers intentionally reduce the ride frequency for their SUVs is they try to maintain their overall GRIP levels on the roads!!!

Another thing I could think about is SUVs are more prone to flip over... So, car makers reduce the ride frequencies for their SUVs, as they are not supposed to be driven THAT FAST!!!

I think I may know why the ride frequencies of SUVs are lower than those of sedans in general...

I think the reason should be... SUVs may be used on OFF ROADS. High ride frequency cars are good on tarmac but definitely not so good on gravel!!!

In my opinion, car makers may also adjust the dampers for SUVs to let them keep being well-damped even at off-roads conditions...

(I also guess the damper settings on SUVs could be a little stiffer than those on sedans. So, the rides of SUVs are usually not as comfortable as sedans)

So, are SUVs softer than sedans??? I think the answer is Yes and No!!! Yes is SUVs feel stiffer(uncomfortable) because of stiffer dampers but No is SUVs are actually softer than sedans because of the ride frequencies...

So, I think I was right on maintaining grip for SUVs...

On gravel or off roads which have lower grips, the SOFTER suspensions are better!!!

PS: That's why those super stiff supercars are always equipped with SUPER BIG tires. The stiffer suspension the lower grip, actually!!!

This guy is not a professional racing driver but he drove a stock IS500 at Virginia International Raceway(VIR) and was faster than Car and Driver's lightning laps!!! (C&D's was almost 2 seconds slower!!! You must be kidding me!!!)

The thing becomes even more weird... This IS500 has a softer suspension, weaker brakes, smaller and less sticky tires, a worse differential, etc. but C&D claims this IS500 is faster than RCF at VIR!!!

So, I searched the Internet and tried to find out if anyone was also like me and wondered this outcome???

Guess what... Actually I found there were some discussions about this at RCF forum. One of replies said C&D hired different drivers to test the cars, so there could be some differences...

Then, my question is... Why every time the slower car was Lexus, not BMW???

The below is the ride frequencies for RX-8...

Like other Mazdas, the ride frequency of the stock base suspension is a little low!!!(I'm also a bit surprised)

However, the good news is... Mazdaspeed is not soft anymore!!!

PS: Mazda could adopt stiffer dampers for their cars. What people feel about the stiffness(uncomfortable) of suspensions, usually are from dampers, not from springs... (However, the ride frequency is based on springs, not on dampers except those dampers are extremely stiff which are very rare and impractical)

It looks like the new Civic Type R is about as fast as the old one, FK8... (big tires will slow down the car)

However, on tracks new Civic Type R should be a bit faster thanks to much bigger tires. (That's why the new Type R stops a bit better) But, you have to push it to 10/10 to tell the differences!!!

In addition, the bigger tire the more noisy on highway!!!

As you see... This trophy truck, an off-road master is very soft!!!

So, Camry may not be that good on dry tarmac but could be better on gravel or wet!!!

(Remember, everything has pros and cons. However, there is one exception... That's reliability. The more reliable the better, ALWAYS!!!)

PS: You may wonder why this trophy truck was slower... That's because the road was TOO SMOOTH. That truck needs something rougher!!!
