Default Question about rear upper strut tie bar.

I have been thinking about purchasing the rear upper tie bar to match the front, what kinds of handleing benifits would this give? (neuspeed race springs, azenis on stock rims) thanks.

Slim to none.

If you want handling to improve, replace the Neuspeed springs with stock springs.

reid is right, it will stiffen the chassis a bit in the rear, promoting oversteer, but since the rear is so stiff already the effects are minimal. Your neuspeed race springs have a higher spring rate in the front by a significant margin if memory serves, this induces understeer, which is bad (from a performance standpoint). what dampers do you have mated with the springs?

What are your purposes for the car so we may give you the best suggestions?

There is no be-all, end-all suspension.

Which series are you racing in? I can't believe you're competitive on Azenis.

Dreaded Push? That might (i mean DOES) have something (i mean EVERYTHING) to do with the F/R spring rates you are using right now.....

and btw - the rear upper strut bar will not get rid of the push you already have. maybe lessen it, but not eliminate it.

Oh, you are talking about Lapping Days/HPDE's, not racing.

Anyhoo, if you seriously want to get rid of the push you have, you have to change your springs. I quote Aleph:

Your neuspeed race springs have a higher spring rate in the front by a significant margin if memory serves, this induces understeer, which is bad (from a performance standpoint).
You want to get rid of the push? Get lower spring rates in front, higher in rear.

Depending on your experience level (and i'm by no means a pro ) you might want to put your stock springs back on (the neuspeed race springs are WAY too stiff for your stock dampers to function effectively, you may have blown them out pretty thoroughly depending on how long they've been on the car) and then take some time learning the ropes on a stock suspension, you'll be much safer doing so, and the Type R is a blast to drive stock, you don't need upgrades as much as you need practice/experience. After a year or two of autocrossing/trackdays you'll have a much better idea of what you as a driver want your car to do, rather than letting the stuff you've got on the car dictate what kind of driving you have to do. Once you've got some time under your belt, i'm sure you'll have picked up a ton of info about suspensions and whatnot from the friends you make autocrossing and tracking.

As for examples of setups, i just put some bilstein/eibach/ground control coilovers on my car, with 450 lb/in. springs up front and 600 lb/in. springs in the rear....RR98ITR on this board (Scott Rinde) had them built, and they're way more badass than i need, but I'm very happy with them and look forward to my first track day on them at the expo. Check the page in my sig for pix...but I've got 2 years of autoX and track days on the car already, and it was perfectly fine stock...and as we all do, i've got alot more to learn
