    The squire suspension set up would definitely increase understeer in a FWD car. The old set up is better suited for your car. A squire set up works great on a front engine RWD car.

      Yup. Already decided to put the rear 10k springs back on, plus a couple other handling changes.

    • @FCustureri
      @FCustureri หลายเดือนก่อน +1

      Exact F:R coil spring rates also depends on other factors such as F/R motion ratios, weight bias, sway bars, tire setup, etc
      But yeah the gist of it is increasing the relative spring rate on one end does seem to cause that end to lose grip sooner than the other.
      As I also found with my 04 AP2 which came stock with similar F:R spring rates and sway bars. Going to Ohlins which came with 10k F/8k R made it understeer way too much for me (on "square" tire setup even).
      Going to 10k F/10k R got me back to the balance I missed

    Totally agree with larger diameter rear sway bar, also have you contemplated using a wider front tire, ala Porche, but back assword cuz FWD. Alternatively you could try softer front shock and or springs. I realize everything cost $$$. Been there and done that.

  • @roadfordays
    @roadfordays หลายเดือนก่อน +7

    I have no idea how spring rates translate to ride rates on the Integra's specific geometry, but given an assumed front-biased weight distribution, something approaching square spring rates is probably correct for "flat ride" and maximum mechanical grip from a ride motion standpoint. However, a flat ride setup on a nose-heavy car will require a beefy rear sway bar to restore the desired lateral weight transfer bias. That's why good-handling FWD cars tend to lift the inside rear wheel. Get the beefiest rear bar you can find and you should be good to go.

    • @TassieLorenzo
      @TassieLorenzo หลายเดือนก่อน

      You always want a higher natural frequency in the rear than the front on a front wheel drive sporty car. At least 10% higher in the rear, if not 20-30%. E.g., if the front is 2 Hz, the rear should be 2.2-2.4Hz. That's typical for OEM spring rates on sporty FWD models, it's how Fords and RenaultSports get that nice pivoting feeling. 🙂
      My preference is to do that spring rates and not with a huge rear swaybar (the OEs don't use a huge rear swaybar to do it). Since everyone says WRXs understeer, I had a huge rear swaybar and stock front swaybar on my GC8 WRX (with square spring rates 7kg/mm front and rear, it's strut front and rear, so I guess about the same motion ratio at both ends) -- the way it handled was spooky, lol. You want that pivoting feeling in a front wheel drive car, but the way the rear wanted to overtake the front with that setup was too much lol.

    • @TassieLorenzo
      @TassieLorenzo หลายเดือนก่อน

      @@Zygrene May I suggest looking up or measuring the motion ratios, estimating the corner weights and calculating the natural frequency front and rear? You're looking for a natural frequency that is about 10-30% higher in the rear than the front. Whether that's by going softer in the front, stiffer in the rear or both, that does make the ride a bit hoppy but that's just how sporty front wheel drive cars are. 🙂

    • @roadfordays
      @roadfordays หลายเดือนก่อน +1

      @TassieLorenzo you are right about the frequencies in general, but sway bars do not affect those frequencies (okay, they affect them a little during cornering, but that's beyond the scope of anyone to calculate without a supercomputer, as it likely changes dynamically with lateral load). Sway bars are only the icing on the cake you use to fine-tune handling balance after you have achieved the desired frequencies with main springs. In the case of any car with a massive front/rear weight imbalance (basically all FF cars), you need that big rear bar because so much more weight transfer is naturally happening up front and the rear springs are relatively soft even after the 10% higher ride rate boost (less weight means a faster ride rate even on identical springs). If you try to balance the car with main springs, you will end up with a rear end riding WAY faster than the front, and it's going to be pogoing all over the place. You cannot achieve balanced handling and flat ride on an FF car without either a big rear bar or reverse-staggered wheel/tire sizes. Many people choose to sacrifice flat ride because they don't know what it is, or they think that's only for comfort. They go slower. The exceptions are cars with full unlimited time-attack, F1, or Pikes Peak level aero, where managing aero loads trumps all other considerations.

    Great job and thanks for sharing. It seemed to me watching that the setup changes did not yield an increase in overall grip and/or that braking instability was just really bad. If it were me, I'd go back on either front or rear springs to re-establish a better baseline and then go forward with bars. This setup didn't want to go fast in, which would make for a long day.

  • @HigeYatsu
    @HigeYatsu หลายเดือนก่อน +1

    If you can get back on track before the next set of mods, it could be a worthwhile learning opportunity to play with damping and see how it affects car dynamics firsthand. You probably won't be able to solve all your qualms with the car, but I think you'll be surprised just how much you can tune motion control with compression and rebound tuning, as long as your spring rates are in the general ballpark and you have quality damping.
    Kind of making lemonade out of lemons with the less than ideal setup changes you're dealing with, haha. The square setup might actually make it even easier to feel out and understand.

    add a thicker RSB you can retain your ride comfort for the rear while improving the rotation of your car. if you can get the karcepts I suggest that but the EIbach 25mm will significantly make a huge difference. without any draw backs for day to day living. you'll also find lesser wear on your front tires because you will not be asking too much out of it because car rotates beautifully. just a win win for roughly $200-500 depending on what brand you get that also translates to faster lap times

    @ioannisioannou7518 หลายเดือนก่อน +1

    It's clear you're dialing things in, some of this was clearly nerves and mild hesitation with entry speeds. Too many cars on track doesn't help either... But all things equal, agreed on a slightly stiffer rear spring rate and rear sway upgrade, although before you shell more cash would first try (as previously recommended) to set your Ohlins dampening in the rear almost to full stiff (1-2 clicks) then have front ones at maybe 2-4 clicks, in order to get rid of that mild understeer. Slightly higher tire pressure rear (mb 1-2psi) than front as well. I am running 7k front and 8k back R&T setup on a AWD mk6 R with 3 clicks front and 2 clicks back (upgraded/fatter rear sway) and its as close neutral as it will ever get. Keep working on it and don't get discouraged. Knowing and fixing the issue is progress even if your times don't always reflect the gains.

  • @davidzebar6876

    @wolvesbrigade1700 หลายเดือนก่อน +1

    So I wanted to add my two cents even though I’m by no means a professional just played a lot with springs on the sim. There are two sides to this coin; A square setup is a good idea for FWD depending on weight distribution and I think you highlighted some of the problems in the video, u have the same alignment and dampening settings with a totally different spring and that just won’t do. With the rear being less likely to rotate. You need to make dampening and rebound changes in order to promote that rear rotation. As well as an alignment (I’d look at toe and rear camber) that help with that as well. On the other of the coin; going back to that 10K will definitely get you that rotation and then with things like rake and other dampening changes, u can stabilize it under breaking. I feel both routes are do able just more changes are needed in order to accompany the significant spring change. ESPECIALLY your dampening settings in reference to the 7K Square setup! Thats just my opinions and I’d love to discuss more with you to hear ur thoughts as maybe an 8.5K or something along those lines is what you need. (Idk if it’s possible to obtain a spring rate like that)

  • @z06van21
    @z06van21 หลายเดือนก่อน

    Unfortunately, you only have one way adjustment on the Ohlin R/T. I have MCS 2-way remotes on my 718 GT4. As a general rule, the stiffer the spring rate you go, the less compression you need, but the more rebound damping you need to handle that spring rate.
    With 1 ways, the compression and rebound clicks are married to each other, with the larger change coming from the rebound side.
    When you start playing with different delta's front to rear on spring rates, you really need a 2 -way damper to un-marry the compression from the rebound.

    7/10 might work well. 6/10 is too tail happy, 7/7 is too pushy, 7/10 might work well. On your 6/10 setup you needed a bigger front bar, on your 7/7 you need a bigger rear bar to handle more roll couple, so I'd try 7/10. Although adjustable bars are cheaper and easier and dont require re-alignment.

      I have a FL5 and am been following the thread closely and plan on doing the same to mine eventually.

    I'd assume since the fronts are struts the motion ration is about 1. The rears are not struts and will have a motion ratio above 1 so you would never want to go equal rates in a fwd car. The rear should be higher. You could band-aid it with a stiffer rear bar but you should go with stiffer rear springs. ultimately you may want a stiffer rear bar but you should start with stiffer springs
