Replaced my stock stuff with new kyb gr2's and tein s-techs it rides alot smoother than I honestly expected for a cheap setup. OP it would be advised to change the struts if the funds allow but if not you should be safe for awhile. No real answer for how long the stock struts will last when used for lowering, some have had failure pretty quickly well others have had zero failure.
It is extremely unsafe to drop your car with the stock shocks. Jk
I used the s-techs but I replaced the shocks with the KYB's at the same time and I love the ride, it is a bit more rough than stock, but it looks great. Overall I would rather have smoother ride.
I ran tein s-tech springs on stock struts, took about a year and a half to blow a strut. As mentioned above, if you have many miles, i.e. 60k+ I would strongly recommend getting some kyb struts while you're changing springs.
Thats worrying! Wasnt aware that dropping the car with aftermarket springs on to the stock shocks was potentially dangerous and shortened the life span of the shocks. Iv drop mine about 2 years ago with the tein s-tech on the stock shocks. Iv noticed some creaking when driving over speed bumps, but that could be from the upper mount on its way out.
Mine just blew the front left strut, it's not something that is going to send you off the road, careening into a busload of pregnant nuns or anything. It's just that the shock starts losing oil around the shaft seal, which means it doesn't control the bounce of the spring as well, leading to a more bouncy ride when hitting bumps.
im have tein lowering springs on stock struts. my car has 115,xxx miles. still no problems. i forgot when i put them in. maybe around 60,xxx? still no problems (knock on wood!!!!). i dont track or autox. just sprinted driving once in awhile.
The point of this is to put the info all in one place. This is for non-stock sizes, of course.
The info needed is:
-Wheel brand and name
-Wheel diameter and width (front size & rear size)
-Offset (front & rear if they differ)
-Tire size (front size & rear size)
-Lowered or not
So happened upon a LED red strip an figured it may just fit on the Toycar.
Took a careful bit of surgery, dreading dropping the housing on the shed floor and breaking near completion.
Still yeah I'm happy with the result.
