**Bump**



Flash: Did you happen to find the Koni front strut info mentioned earlier in this topic...?



Also does anyone have a set of the progressive springs [190-230lb] shown on the Paragon site?? If so, how well do they work..?

I have the H&R Progressive rate lowering springs form Paragon and have been entirely satisfied with them along with the Koni, Yellow strut inserts. I installed 28mm rear torsion bars and reindexed to get the rear lower to match the front. Also using the M030 anti-sway bars with delrin bushings. I love it! Good luck, Bob Blackwell.

the H&R springs only dropped the front 1" - that was "ok" when you dropped the eccentrics all the way - but, everything i have seen on the hypercoils has been a real world drop of 1.5"- this results in a bad combination when you fail to change the rear



bob did right and put in the bigger torsion bars - that allowed him to both balance the spring rates, and set the ride height



s cal - call pete at rs barn when you are ready to ship them your housings - they do not go together in DIY fashion like the yellow sports, and really need to be done by professionals - not something to be done at home

Actually I was considering the Koni's from Paragon - they also provide rebuild service at a reasonable price. And try a light coil-over shock for the rear.

A 1" drop is fine; I hit my splitter now at stock height, so i don't want to go much lower than an inch.

Flash: I thought you had a model or part number for the "other" Koni struts mentioned on pg 1 of this topic...?

agreed - 1" is about all you can do without constantly nailing the splitter, and even then it will require paying attention



as for the struts i have, i had them done and sent to me - they are dual adjustable hydraulic (separate rebound and compression settings) versus the single adjustable koni yellows - they work much better, but that is also why they cost more - they require a different installation, that is more complex than the simple job of modifying the housings for the yellows - definitely not a DIY - i have not been able to find the model number, as all of my files are still in disarray from the remodel



if that's the way you want to go - just call pete when you are ready to send out your housings



note - until the kit is ready for the shocks i have been playing with, adding a coilover to the rear will require reindexing the torsion bars to get the ride height right - at that point, you are possibly better off just changing torsion bars

Here's a quote from Pete @ RSB:

"I'm working on a oil shock setup for rear so you can use 100-150 springs w/o reindexing". I would guess they'll be closer to 100..

I haven't seen this new product come up yet, so it's a wait and see... And, he didn't have anything with oil for the front.



Yep. this is another "what are you going to use the car for" mods. A higher-end shock may not be a logical/practical choice for a car primarily driven on the street. So whether it's best becomes a moot point.

yes - however, the amount of lowering is still limited by the torsion bars - to go below that limit, you must reindex, replace, or eliminate the torsion bars - at least with the kit, it doesn't raise the car like all of the other coilovers - nor does it allow the springs to fly free under full drop - no comparison to gas either



this is indeed the slippery slope though - not for everybody either



i picked up the idea from one already out there, but not really finished - i have 2 cars now out there with the oil shocks on the rear, and they are both working well, but the conversion was neither easy or inexpensive - each kit is different - the availability of the rear kit will be largely determined by the interest - but, you can still count on the fact that it won't be cheap - none of the coilovers are though - there won't be any savings to be had by trying to source parts either - none of the parts (except the springs) are "off the shelf" - even the shocks get some treatment before they are ready



as for the fronts, having now had both, the oils are a lot better - much smoother and more comfortable ride than the yellows - also much more precise in hard corners - whether or not it is enough of an improvement to justify doubling the cost is very subjective - for me, it was



he does not stock the oil setup for the front - you have to send him your housings to be done
