Just curious on the feedback. I'm running the stock setup at the moment (350cst) and don't think I like the feel of the rear progressive springs. Does not feel consistent for me. Ordered the 2.5 spring to put in the rear and going to try it out. I know a lot of the setups call for 2.7 all around but I'm worried about twitchiness combined with soft oil.
I've mentioned this before, but XRAY's oil has been measured to run heavier than rated. So, 250 is actually closer to 300, 300 is just over 350 @ 354.

I suspect that the setups you are seeing are using XRAY oil, and as such should be adapted accordingly.

At a local asphalt track, I didn't like 2.7's all the way around either. I'm running 400 cst all around, which is very close to XRAY's stock 350. I've settled on, like you mentioned, 2.5s in the rear with 2.7s up front.

Of course, all tracks are different, and carpet is certainly a different story, so testing is king.

I just re-read the source page for that chart, it's been a few years. It's possible that the XRAY ratings aren't as far off as that chart leads to believe. Since I have no other frame of reference, and my personal testing shows similar feel, I'll stick by my statement, for now.

Good information, thank you.

The CPS chart seems to show that XRAY's oils are nearly dead on now, they actually seem a little too perfect, but whatever. Given that, I have no idea why 250 cst oil would work, every time I try going something that low the car is just terrible, but like I mentioned before...every track is different.

I noticed the XRAY oil is quite a bit harder recently. Typically I use SWEEP oils and the 400 from Sweep feels softer than XRAY 350. I am slowly making the transition over to AE oils though, where it seems like XRAY 350 is similar to 30-32.5 AE oil.

I've been running much more oils in all of my on road cars and they have been fantastic! Much more for shock oil and ae for diff oil, but I will be switching over to either sweep or x ray for diff fluids.

I have used the attached chart and found it pretty accurate between Xray and AE oils. I find for outdoor asphalt that its hard to beat AE oils in the 30-40wt range (~350-500 Xray).

Yea, that's the chart I posted a couple posts back, it seems to be inaccurate...given newer information and newer XRAY oils.

My T4 yesterday at the BRCA Winter Meeting (Reedy Race Of Champions Format) Everyone on 10.5 boosted.
Sadly didn't make the top 32 (40th), 14s off FTD
Tried all weekend to find a good combination of rear grip and turn in, especially through the chicane.

+ YouTube Video

My new T4 is on the way. My T3 '12 suffered a huge main straight crash on the weekend, and I was always planning to eventually update - now is the time.

Can't wait

Hey guys ,

I currently have an Xray T4 that is setup for blinky

Anyways I am planning on buying another T4 to build up a "mod" car however I am just wondering if Xray is going to release a T4 2014 or something in a few months ?


Just debating on what I should do or if they even will release another car in a few months .

I love my T4 and wouldnt really care to have another but if they are going to release a new one ...Its just smarter to wait I guess and get the freshest one on the market rather than having two lol


I dont know about you guys but every time I look at my T4 and think ....... Really what can they change from now until 6 months from now lets say lol I dont get it .

Xray are like clockwork with their TC releases. The next car won't be out until the end of this year, so you'll get a full season of racing out of the T4 if you buy it now.

Also, any changes are likely to be fairly minor and available via an upgrade package, since the T4 has only just started it's life as a platform.

Be nice if the chassis was a little narrower, motor mount like tc6.1 and spur gear and pulley mount like yokomo
