TRD Sportivo kit questions

[Anonymous]

I'm thinking of purchasing either the TRD Sportivo kit or the (more track-tuned) TRD WayDo Sportivo (check the thread by Dieamond)

I've already fitted TTE anti-roll bars (US=swaybars) and TRD member braces on my '01 Roadster. So I'm really only looking at replacing the suspension struts and coil springs.

I just had a couple of questions. Perhaps if someone has already fitted or tried a car equipped with the Sportivo kit, he/she could answer them.

=> How stiff are the Sportivo springs compared to stock springs? (I know the Sportivos are 15.6N/mm (FR), 33.6N/mm (RR) and approx. 20mm shorter. But I don't know how they compare to stock springs...

=> Where exactly do you fit the member spacers included in the Sportivo Coil Springs kit? :

Spring Kit - 4 springs appro -20mm, and Rear suspension member spacer to change rear roll centre

can't give you ratings but trust me they are a lot stiffer, certainly harsher than teh TTE/eibach springs

the spacers, assuming we are talking about teh flat black thing that looks like a double ended ring spanner? These go between teh chassis and teh grey crossmember at teh back.

while under teh car look up at teh crossmember and you will see 2 bolts either side.

Thanks for your reply.

Do you think that is mainly due to stiffer springs or the stiffer TRD shock absorbers? You wouldn't have the TTE/Eibach spring specs by any chance   s:) s:)  ?

Exactly, black things that look like double ended ring spanners, that's what I can see on the product photo.

If it fits between the chassis and the grey crossmember, it shouldn't modify the position or angle of the rear suspension? Is it just a reinforcement then? I don't understand what the "rear roll centre" thing is?

this where we could do with SteveJ todo teh math as I get a bit confused on it.

But it will change your camber angle and your roll centre.

You can probably get the whole Sportivo package for less than getting just the springs and shocks. And you can always sell the parts you don't need  s;) s;)

I think he wants the adjustable struts, as he's doing some track  :-) :-) :-)

Ah, you're right...he even mentioned it in the other thread  s:oops: :oops: s:oops:

Adjustable struts rule! It's really cool to be able to set them to "don't break my back" mode for everyday driving and then set them to "go-kart" mode for a track day...

My worry is that the WayDo Sportivo springs are so stiff, that even setting the shockies to the softest position would still make the suspension too stiff...

I wish I had tried out Diamond car last June when I saw him at Dijon/Pouilly, as it was already fitted with stiffer H&R springs (IIRC...)

They are nice. I had the Koni adjustables in my Mk1 MR2...but in the end I just found the best compromise for track&street and left it there. I feel the Sportivo is just that, sometimes ona rough street I feel like it could be a little softer and on a track a little harder. But it's actually so dman perfect, that I probably wouldn't adjust it, even if I could  s8) s8)

Now I don't know about the streets in Geneva, but I'd guess the normal Sportivo springs should be just enough. Assuming you do most of your driving on the streets and don't race the car (at least too seriously)...

Just found where the member spacer fits...



This should affect the camber angle and probably improve the geometry of the lowered suspension.

Does anyone know if a similar spacer is included in the WayDo Sportivo kit (or available separately)?

Does anyone know how the Eibach/TTE coilover springs compare with the Sportivo springs?

I know they are 1cm shorter, but are they stiffer or softer than Sportivo springs?

TTE+stock shocks is a lot softer than Sportivo (springs+shocks), not sure how much that actually tells about the springs though  s:? :? s:?
