900 is thin compared to the set up sheets that I have seen. Last season I have tried 2k but I didn't like it.
The car (T3, btw) was breaking out when going on throttle out of the corner. I can (and probably will) give it a try again.

I have found some improvement by removing a screw on the bottom of the car (from the motor mount). This should give the car a bit more flex I believe.
On the bulkheads (for the spur) I also don't have any screws, can I remove more from the upperdeck? This to get more flex. I did also remove the alu stand already.
I also read something on raising the top deck with 1mm spacers. This should also give more flex. Is this correct? you would have to place 12 spacers? Or 8 as I don't have screws on the spur bulkheads.

Yes, you can raise the topdeck with 1mm spacers. This will increase overall flex and since you are now lifting the topdeck off of the center bulkheads, will be more noticeable at the rear and make it more consistent too. In my experience on carpet, this makes the car react a little slower to steering input and direction change, but it will generate more traction in the middle of the corner. Since you are only running the 8 screws, you would just need 8 shims.

I tried the raised (0,75mm) upperdeck today, not really sure about it yet. My biggest problem it getting out of a corner without oversteer or loosing it completely.

you don't need the lower layshaft mounts - although the they are 1mm shorter the ball race is not lowered and stays at the same height as the older 16 layshaft mounts. In fact with 1mm lower layshafts the ballrace still touches the topdeck which is most racers still shim the top deck so it clears the ballraces. so you can save some money and not bother buying them.

XRay T4 Progressive Shock Springs
Hi guys
I bought a couple of XRay's T4 shock springs to compile them as a set and some of the springs in my set consists of 2 pairs of 2.5-2.8 and 1 pair of 2.3-2.6 dual rate progressive springs.
Based on what XRay describes for these expensive progressive springs, the springs will change its spring rate during cornering progressively. However, I just read an article that mentioned short springs like T4 springs can't really have real progressive effect as they aren't long enough to produce additional coil at its end. Therefore, may I know XRay T4 progressive springs really have progressive effect during cornering (I'm a noob in RC and can't really feel the progressive effect).?
In addition, in a very low grip technical on-road track, is it advisable to use 2.5-2.8 progressive springs for the front and 2.3-2.6 progressive springs for the rear as I heard that softer springs at the rear would produce more rear traction (as my car would sometimes sway off at the rear during mid corner and exit corner?
Look forward to your helpful advice and thank you.

Either way, the progressive springs definitely work as advertised.

Progressive springs for me have felt ok. Some tracks like it better then others. For me, the car rolls onto the outside easily but mid corner or just before mid corner, you get into that stiffer rate, and the car induces a hint of a push. Sometimes this is remedied with a different front swaybar. But, it all depends on driving style or track layout. I will say it's not often you'll find anyone running progressives on the rear-typically it's a front tuning option for a bit more corner entry steering. Best way is to test it back to back and come up with your own results on how it works best for you.

Also, I realized that when I loaded my battery, with 2.5-2.8 springs in front and 2.3-2.6 springs at my rear, the front seems to be softer than the rear when pressed down. Is that normal as the front springs are harder than the rear and my shocks are of 0 rebound.
Thank you.

Thank you and R Dodge for the prompt reply. I just learnt from you guys that progressive spring is a tuning option for front steering. May I know if I'm running my T4'16 (with XRay 2.5-2.8 progressive springs in front) on a low traction on road track with multiple 180 degree corners, what XRay spring rate would you guys recommend so as to gain more rear traction and reduce the chances of my rear from spinning out? I will try out 2.3-2.6 progressive springs on my rear the next time when I run my car on the track, but still want to hear some advices from you guys. I suppose it should be a softer one for the rear isn't?
