It’s been holding up well last time I checked. I’ll probably go with kmac camber kits if I decide to switch to vtf’s.
btw. my camber was -2.2 front and -3.2 rear

Thanks, Alexasa... not to hijack this thread, but are you planning to get camber kits for the rear?

I was talking about my camber previously. Dunno if you though those were the drop in inches haha. I have - 2.5 on the front and -3 in the rear. My previous set of PS4S only lasted 12000km with tons of inside wear.

Those 12,000km included some track days, right?

Toe is good after alignment. I am actually facing a very strange issue. May be you might be able to chime in.

When I am getting on an inclined pavement from the street at an angle, as in turing into a steep pavement (does not happen over the the normal ones) I am heard a metal on metal scraping sound when getting on the surface. I got off the car and checked what just happened. And looked like my passenger front wheel was fully loaded (compressed) and extremely tucked in, while my driver front and passenger rear was completely off the ground, with rear driver also compressed, the front passenger side being the most compressed though. I have a 5mm spacer in the front making a resultant ET of 30 with a 8.5J front wheel. Never had this issue before the H&R sport springs even though the car sat lower than it is currently. It is almost like the current springs have been cut short, so it pulls the tire off the ground much sooner than before, I dunno if that makes sense. But the thing that bothered me was the scraping sound, I have heard it before when the inner side of my wheel was hitting the suspension knuckle over the its very characteristic bump.

I have lifted the car off when I put the spacer in and there was a good a 3 to 4mm space between the wheel and the suspension knuckle at its tightest point. I verified this is the gap while the tire was on a flat surface (loaded wheels) during alignment. Is it technically possible for this gap to decrease when one tire gets compressed a lot? Cause ever since I got the spacer, I have never heard the wheels rubbing the inner knuckle ever. Super weird.

I guess I have to extra careful getting into inclided surfaces going forward. But I Have no idea what else I can do, cause my steering was pointing completely straight while I heard this sound, so it definitely was not my tires rubbing on the inner fender. Also my traction control light came on while I was trying to go over the surface. Probably because one of the tires were freely spinning.

are the springs in this VTF setup stiffer than the lowering springs? that metal sound might be the springs hitting each other - many times they put a sheathing on them to reduce this (as seen below in clear surrounding the springs).

fronts on the HAS setup also have helper springs - are those suppled with the VTF and were they installed? (sometimes people leave these out to get a lower set-up)



helper springs

The springs are not stiffer for sure as the car feels more compliant overall and much more comfortable. I do not think the H&R comes with with that small spring in the buttom in the fronts.

Could you take a pic of the VTF spring set so that we can have a photo reference for the future. When I get my KW HAS set, I will post a photo here. That way, in the future, anyone can compare the two offerings before buying.

In my search for adjustable springs for the C43, most of the websites selling VTF and HAS only show stock photos of their product and not the actual C43 kits.

So I think it would be great to actually be able to see them.

I’m getting my HAS kit in about a months time, because Germany is out of stock at the moment and they have to be produced.

I didn't get a chance to take a picture of my VTF but here's a picture I had before that I downloaded from one of the suppliers.


The ride is the same compared to the stock springs. So far, I love it. I will be putting my 20 inch rims in the next 2 weeks and might have to adjust the height.

Very often rather than not, the pictures on retailers website are just stock photos. Sometimes they even state that the photo may not be of the model that your purchasing. Are you certain that’s what your set looks like?

Thanks for your help. Got it installed yesterday and I love the drop. Same height as yours. Kevin and his team did an amazing job. We might have to adjust it after I install the 20 inch rims.

No problem! 20 inch rim is a bit too much in my opinion. But each to their own. Which rims are you going with?

Actually I need to verify if my setup has helper springs or not. The absence of helper springs will explain my problems:

@Sethseb Can you pm me your phone number, We can verify this together then. Should have gone with the HAS. Damn it.

thus why i asked. helper springs are great for full droop situations. But they can also be "built" in with a more condensed coil section.

i'm not sure if VTF is supposed to have them or not - or if they have them built in to the primary spring.

I am confirming this in a bit. Just got off the phone with my distributor. They told me there is supposed to be 4 helper spring that is supposed to come with the setup. May be they missed it for mine? Or I do have them, but I cannot see where they are for the life of me.

It’s a shame they don’t make them for Estate or Cabriolet.
