With all leaks, find the source by carefully examining the GDU. Anything is possible, but common sources that I have seen: Hose clamp is not tight overfilling and oil exits the orange vent oil seeps...

I think you have the wrong part number and size. You need 7mm width, not 8.5mm. For SR3, I use this: Oetiker Stepless 7mm Band (16700042)Oetiker Stepless 7mm Band (16700085) Also, no need to remo...

@rojid If you don't already hate me, you will now. To be fair, I asked a pro technician with 40 years of experience the exact same question. I was scratching my head, and I texted Jonathan from Gr...

Yes. Use cutting fluid and take a little off at a time to keep your cutting bit cool.

When I needed wheels, I purchased sets from US Radical Dealers WISKO and Group-A. I believe that the US supplier is Radical UK like most all Radical specific parts.

@rojid Yes, I always use a 1/2 inch torque wrench set to 80 foot pounds to tighten the lock nuts ... with a 1/2 inch wobble extension and 1/2 to 3/4 adapter. If you look at all of the posts on th...

I just use the red 271 loctite on the threads of the lock nuts. No problems with loosening, and no problem removing the lock nuts with a 1/2 inch impact wrench.

Which Generation of Radical SR3 do you have? I assumed that you have either gen 3 or 4 because you referenced the drop height table which is found in Gen 3 and Gen 4 owners manuals. I am unsure whet...

This is the overflow breather. If you over fill the GDU oil, it will exit this breather cap.

This looks like the damper spring cap. It fits between the spring and the rebound adjuster.

Some photos. First photo shows the old grease in the tripod joints compared to the new grease. Old grease has turned from brown to grayish-brown. Attachment : IMG_7335.JPG Tripod greaser ...

According to this discussion, CV joint grease is too thick for tripod bearings, and I agree. I have seen techs also use Lucas red and tacky, and I have seen those tripods fail prematurely. GKN ...

@rojid Yes, you have the right idea in your description above. That is a good video, however for race cars I would only use GKN tripod grease. It is expensive grease, but according to GKN and a kno...

You do not need to find the actual ride height because this is a computed value based on the drop height. The factory has done all of the careful chassis height calculation based on drop height measu...

You are in the correct ballpark for drop heights. In the SR3 RSX manual (Gen 3), there is a drop height table for Dunlop and one for Hankook -- I guess because they are slightly different diameter ti...
