Rod Bender

@rjbender That's really nice work. My wheel nuts and wheel surfaces look very much like your "before" pictures and seem to work ok. But it does concern me when I look at it. I have found that any lub...

My side skirts are about 52mm from the ground, both sides, so 33mm does sound quite low. I would start by establishing the actual chassis height (not ride height or drop height), measured from the st...

Posted by: @rjbender The only slightly tricky thing is checking/setting the 'free play gain' which is an adjustment that you make on their slave cylinder That is a fact. I spun and burned one of th...

Hi Willem (@illwillem) welcome! What chassis number car do you have? I haven’t done the change over but it sounds like you have the parts list about right. You could likely modify your current tail...

The main problem was that the two batteries were unlinked, which caused drawdown in the main battery, also resulting in the charging system to be inoperable. I suspect this prevented the ECU from get...

Potential solution. Bad relay was causing second battery to not link with the main battery update. Car is fixed. New engine runs well. Three issues found and corrected. I’ll fill in details tomor...

A few years ago, in an effort to make some safety improvements to my car I decided to install a Halo (Lateral head restraint). I ran into challenges immediately because I am a "body tall" person (mea...

my car does not have the spin safe clutch. Can someone explain the mechanics of how that operates? I am assuming it is purely internal, thus should I consider getting this modification during the up...

@charleyhradicalsportscarregistry-com will do Charley. I just collected an additional 46 second run by holding throttle. vbat starts at 10.42v, jumps to 13v while I am holding throttle, then return...

Rod, I don't have an answer but I noticed recently that one of the sensor cables which is close to the exhaust is shrouded with a loose heat shield tubing to protect against radiant heat from the exha...

As DavidF said Rod, get some heat protection on there. Unfortunately it is bending it back over itself and cable tying to the chassis leaving as much as you can from the exhaust. As you say a port in ...

@charleyhradicalsportscarregistry-com Thanks Mr.C....

That is the spark plug that is used in the 1340 and 1500 engines.

raider89, using the clutch like that is normal use and shouldn’t cause any issues. I would recommend giving your Radical dealer a call. With that said, If you want to do some trouble shooting I woul...

raider89, As Rod is 100% correct (as usual). Radical recommends overhauling the 1500 engine at 40 hours TOTAL Time. Many find this unintuitive because to use an extreme example if one engine was idl...
