View Full Version : rear end

2002.07.30, 01:27 AM
I need some info on lowering the rear end of my vehicle... besides taking out the triangular plate in the rear and having a bouncy, weak rear end is there any other way? do the CF H-plates need the triangular spacer?

Besides this, does lowering the front end have a detrimental effect on front end suspension? ie. shorter travel, I cant see that it does being that it isnt designed to soak up bumps of that degree anyhow, but ask someone who knows I always say......

And one last thing.... Can the X-Speed motor be run without a turbo without damaging the esc?

Help is much appreciated

well.. IMO you really shoudn't take out the rear triangle, removing it changes the suspension geometry and makes things worse.
Lowering the rear should be done at the other end of the H-bar.

Short of something coming in contact with the ground and/or fenders there should not be any direct harm in lowering the front end.

On anything that is not absolutely smooth lowering might make the handling worse as you will make contact with the racing surface more often.

It's a trial and error process and what works for me might not be the most comfortable setup for you.

And no, you don't _need_ a tubo with an X-speed... turbo does improve the performance.

so how can you lower it from the other end? (H plate)

Add washers/spacers between the H plate and the motor pod....

...Unless you use an O-Plate! ;)

ok, i know i ask a lot of questions.... why not an O plate and how do u lower an o plate?

The O-Plate doesn't need the triangle to function. It's a new product that will be avialable for pre-order very soon.

you mean a premaid o plate right?;)

I hate to put a damper on this, but you cannot lower the rear-end.
You can only raise the motor mount, which in turn lowers the H/O plate and (sort of) lowers the ride height of the H/O plate, but not of the motor mount itself.

When doing this, ensure you are running on a smooth, equal and flat surface, otherwise the screws in the H/O plate will catch on uneven surfaces.

with my recently bought sedan with Imprezza body, i was able to lower the chassis (not the motor caseing) by the following methods:

Front end- i raised the knuckle arms by placing retainers (you can also use washers) underneath them which act like spacers. The knuckle arms rests on these which basically causes less suspension travel. not so much though that i worry of bottoming out. best off all it gives the front wheels a tucked look with no fender rubbing.

Rear End- as mentioned already, there's no way to lower the rear axle because of the motor casing's design. So to match the front end i had to lower the rear of the 'chassis'. Afterall, that's about where the sides of the body mounts. i removed the rear suspension spacer (that triangular piece) and replaced it with the spacer included in the Rear Roll Shock Set. It's rectangular shape fits neatly under that part of the H-plate mounted there. Since it's much thinner than the stock spacer, it lowers the rear chassis (and the body as well) by that much.

On our carpet track i'm having to use the softest of the three carbon H-plates which helped to rid the bounciness caused by it's semi rough texture while still providing a good brace for the motor casing. Those fiber H-plates are pretty sturdy.

unfortunately i don't have any pictures but i will say that both front and rear wheels have a semi tucked look and still allows for decent suspension travel. no bottoming out and smooth riding. at least for carpet.

hope this helps.

i did it by using spacers... i only wanted the lowered look, thanx guys
